Overview
NetBackup provides high-performance backups and restores for a variety of client systems including Microsoft Windows, NetWare, IBM OS/2, UNIX, and Macintosh.
Administrators can set up schedules for automatic, unattended backups for clients across the network. These backups can be full or incremental and are managed entirely by the NetBackup server.
1
Page 32

Users on clients can start backups and restores from their client systems. A user on a client can also archive files. An archive operation backs up a file and then deletes it from the local disk if the backup is successful. Once started, user operations are managed by the Netbackup server.
NetBackup’s Media Manager software manages the media and storage devices. Robots require no intervention on the part of the administrator, operator, or the user. Standalone drives that contain a ppropriate media also require no intervention.
NetBackup includes both the server and client software:
• Server software is on the system that mana ges the storage devices.
• Client sof tware is on the system that requires the backup or archive. A server can also be a client.
NetBackup servers and clients can be any one of a number of computer systems as described in the data sheets and release notes for the product.
NetBackup supports both master and slave servers. The master server manages the backups, archives, and restores. Slave servers provide additional storage by allowing NetBackup to use the storage devices th at they control. Slave servers can also increase performance by distributing the network load.

During a backup or archive, the client system sends a backup data stream across the network to a NetBackup server that has the right type of storage for the client. The storage requirement is specified during NetBackup configuration (for example, 4 mm tape).
During a restore, users can browse and then select the files and directories that they want to recover. NetBackup finds the selected files and directories and restores them to the disk on the client system.
The remaining topics in this chapter provide an overview of other concepts and terminology that will be useful when conf iguring and managing NetBackup.
Media Manager
The software that manages the removable media and storage devices for NetBackup is called Media Manager. This software is part of NetBackup and is installed on every NetBackup server. The NetBackup administration interface contains utilities for configuring and managing Me dia Manager.
1
For detailed information on administerin g Media Manager, see the Media Manager System Administrator ’s Guide - Windows NT Server.
Storage Units
The device that stores the backup data for NetBackup is called a storage unit. A storage unit is a logical grouping of one or more storage devices of a specific type and density. The storage devices can be tape drives or a directory on a magnetic disk. Tape drives can be robotic or standalone.
The devices in a tape storage unit must attach to a NetBackup master or slave server and be under control of Media Manager. The NetBackup administrator first sets up Media Manager to use the drives, robots, and media and then defines the storage units.
If the storage unit is on magnetic disk, NetBackup sends the backup to the file path specified during configuration of the storage unit. Media Manager is not involved.
Storage units simplify administration because once they are defined, the NetBackup configuration refers to a storage unit rather than to the individual devices that it contains.

Volumes
The removable media on which NetBackup stores backups are called volumes. These media (for example, 8 mm cartridge tapes) have been assigned media IDs and other attributes so their content, location, and so on can be tracked. The attribute assignment occurs when the media is added to Media Mana ger and can be done automatically or by the administrator. See the Media Manager System Administrator ’s Guide - Windows NT Server for information on adding volumes.
NetBackup master servers keep a media catalog with records about the volumes where backups are stored. Media Manager controls the mounting of volumes on the devices and keeps a volume database with records that indicate where the v olumes are l ocated.
Note: When the storage unit is on magnetic disk, NetBackup sends the backup to the file path specified during setup of the storage unit and records the location in the NetBackup media database. The operating system manages the actual writing of data.
Backup Policies (Classes)
A NetBackup class defines the backup policies for a specific group of one or more clients that have similar backup needs. NetBackup can have a single class that includes all clients or many classes, some of which can i nclude only one client. A NetBackup client must be in at least one class and can be in more than one.
The administrator defines the properties of a class. The properties that can be assigned depends on the type of clients that the class supports and in cludes:
• General attributes that d efine things such as:
• Storage unit to use for backups of clients in this class.
• Volume pool to use for backups of clients in this class. A volume pool is
a set of volumes that the administrator can assign for use by specific classes or schedules. For example, it is possible to ha ve one volume pool for weekly backups and another for quarterly backups.
• List of clients that belong to the class.
4
NetBackup System Administrator’s Guide - Windows NT Server
Page 35
• List of files to include in automatic backups of the clients. The file list does not affect user backups because the user selects the files.
• Schedules that control when backups and archives can occur for the clients.
As mentioned above, each class has its own set of schedules. These schedules control when automatic backups start and also when users can start a backup or archive. Each schedule can be unique with attributes that include:
• Type of schedule. A schedule can apply to automatic full or incremental backups or to user backups or archives. There are also schedules that NetBackup uses only for database backups, such as for Microsoft Exchange or SQL Serve r.
• Backup w indow. For automatic full or incremental backup schedules, this is the time period when NetBackup can start backups of clients in the class. For user schedules, this is the time period when users can start a backup or archive.
1
• Frequency. How often automatic backups occur.
• Retention. How lon g NetBackup retains the data that is backed up by this schedule.
• Storage unit. The storage un it on which to save the data that is backed up according to this schedule (optional and overrides the storage unit specified at the class level).
• Volume pool. The volume pool to use when saving the backup data (optional and overrides the volume pool specified at the class level).
The administrator can also manually start a backup schedule for an autom atic full or incremental backup. Manual backups are useful if, for example, a client system is down and misses its scheduled backup.
User Backup s, Archives, and Resto res
On clients , users can back up, a rchive, and res tore files, di rectories, and raw partitions that reside on their client systems. A user can restore files at any time but can back up and archive only during the time periods that the administrator defines with the schedules. Users can also view the progress and final status of operations that they perform from the client.

Note: An archive is a special type of backup. During an archive, NetBackup first backs up the selected files then deletes them from the local disk if the backup is successful. In this manual, references to backups also apply to the backup portion of archive operations (except where otherwise noted).
See the NetBackup user’s guides for more information on user operations.
NetBackup Catalog Backups
NetBackup provides a special type of backup for its own internal databases. These databases, called catalogs, are on the server's disk and have setup information as well as critical information on client backups. The catalog backups are set up and tracked separately from other backups to ensure recovery in case of a server disk crash.
NetBackup Administrator Interface
On a Windows NT system, the administrator can perform most tasks through a Windows-based interface program. There are also several special operations that require entering a command in an MS-DOS window. These commands are explained in Appendix A.
Starting the NetBackup Administration Interface
Note: It is possible to run the NetBackup administration interface on more
than one server at a time. However, if more than one person is making changes, the results will be unpredictable.
1. Log on to the NT workstation as a m ember of the user group authorized for NetBackup administration.
2. On the Programs menu, click NetBackup and then on the submenu click NetBackup Administration. Th e NetBackup Administration w indow appears on your screen.

Managing Storage Units
During a backup or archive, the backup data is stored on the storage units that you add to the NetBackup configuration. A NetBackup storage unit is a logical grouping of one or more storage devices of a specific type and density. The individual devices that are in a storage unit attach to a NetBackup ma ster or slave server.
There are three types of storage units:
• Media Manager A Media Manager storage unit uses robots or standalone tape drives that
are under control of Media Manager. Media Manager allocates the volumes for use during backups and tracks the media types and locations. Media Manager also controls the mounting of volumes in the storag e devices.
• Disk A disk type storage unit consists of a directory on magn etic disk that stores
the backup or archive data. The following is an example path in a Windows NT file system: D:\NetBackup\backups. A disk type storage unit is useful for testing and during busy periods because it allows quick backups.
2
•NDMP NDMP storage units are controlled by Media Manager but attach to NDMP
hosts and require that you have the NetBackup for NDMP option installed. See the NetBackup for NDMP System Administrator ’s Guide for more
information.
This chapter explains how to set up storage units for use by NetBackup and has the following topics:

Rules for Media Manager Storage Units
The rules fo r adding Med ia Manager storage un its are:
Managing St orage Units
17
Page 48
2
1. When specifying the media server for the storage unit, always specify the NetBackup server where the drives attach. This applies whether or not the drives are controlled by a robot.
2. For each Netbackup server (master or slave), add a separate storage unit for each robot that controls a drive on that server.
• If a robot has multiple drives of the same density, add only a single
storage un it for the rob ot, regardless o f the num ber of dri ves.
• If a robot has d rives with d ifferent densi ties, defin e a separate storage
unit for each density that NetBackup is using. For example, an STK 9710 library configured in Media Manager as a Tape Library DLT (TLD) can have both half-inch cartrid ge and DLT drives.
• If the dr ives an d robotic control are on different N etBacku p server s, add
the storage unit on the server where the drives attach. Always specify the same robot number that is used for the robotic control on the other server (see “Example 2: Storage Unit s on eel” on page 20).
3. For standalone drives on a server, add one storage unit per drive density. For example, if a server has multiple 1/4-inch qscsi drives, add a storage unit that includes all of them. NetBackup chooses the drive to use when it sends a backup to this storage unit.
If there are stan dalone driv es of different de nsities on a server, add a storage uni t for each density.
Before Adding the Storage Unit
Before adding a Media Manager storage unit, set up Media Manager to recognize the devices that will be in the storage units. Refer to the Media
Manager System Administrator ’s Guide - Windows NT Server for instructions. When you have set up the devices, record the following information about them:
• For each robot that you will use with NetB ackup, record the following:
• Robot type
• Robot number in Media Manager
• NetBackup servers where the drives attach and the number of drives that
attach to each server.
18
NetBackup System Administrator’s Guide - Windows NT Server
Page 49
• Media density for the drives in each robot
• For standalon e drives, note how many drives of each media density are on each NetBackup server.
Example Media Manager Storage Units
Figure 2 shows several NetBackup servers that have storage devices. The following examples show the information required for NetBackup to recognize the devices as storage units. The procedure that follows the examples explains how to add this information to the NetBackup conf iguration.

Example 2: St orage Units on eel
The Windows NT NetBackup slave server named eel has two QSCSI drives that together can form a storage unit. The two drives in the Tape Library 8MM (TL8) also form a storage unit. The following informa tion is required for NetBackup to recognize these standalone and robotic drives as storage units:
•QSCSI tape drives The two QSCSI drives are of the same density and therefore must be in the
same storage unit. If they were different densities they would each have to be a separate storage unit.
• NetBackup Media Server: eel
• Robot Type: None
• Robot Number: Not applicable
• Number of Drives: 2
• Density: qscsi - 1/4 Inch Cartridge
• 8 mm tape drives in robot 5 The drives in the Tape Library 8MM are in a storage unit on eel because that
is where the d rives att ach. The rob ot number, 5 in this ins tance, is the one used in Media Manager to define the robotic control on whale.

Maximum Multiplexing Per Drive
Specifies the maximum number of backups that NetBackup will be able to multiplex onto any single drive in the storage unit.
2
• Specify any value from 1 through 32. The default is 1, which disables multiplexing and allows only one backup job at a tim e on a drive.
• F or values grea ter than 1 , NetBacku p sends c oncurrent, m ultiple b ackups from one or several clients to a single drive and multiplexes the backups onto the media. See “Multiplexing” on page 135 for more information.
Adding Disk Ty pe Storage Units
This section explains how to configure a NetBackup storage unit that resides in a directory in a disk partition.
Before using a disk storage unit, configure the disk as explained in your operating system documentation. To calculate the approximate disk space that NetBackup requires as it creates backups, multiply these numbers:
(largest backup size X (number of c oncurrent backups + 1))
+

Specifies th e maximum num ber of backup s that NetBac kup can concu rrently send to this disk. For example, if there are three backup jobs for this storage unit and Maximum Concurrent Jobs is set to two, the first two jobs start and the third one waits.
This setting equates to the Number of Drives setting for a Media Manager storage un it. The jo bs are not mult iplexed.
The number to use here depends on the available disk space and the server ’s ability to comfortably execute multiple backup processes (also see “Maximum Jobs per Class” on page 62). The default is 1.
Maximum Fragment Size
Specifies (in megabytes) the largest fragment that NetBackup can create when storing backups.
2
The value can range from 20 to 2000 (2000 is the default). The Maximum Fragment Size setting is normally used to en sure that the backup does not exceed the maximum size allowed by the file system. To specify no fragmentation, type 0.
For more information, see “Fragmented Backups” on page 446.
Note: If you change the fragment size, you can still restore backups that were written with the previous fragment size.
Changing St orage Unit Attribute s
Note: We suggest that you make changes only during periods when you are
not expecting backup activity for classes that will be affected by the changes. This allows time for you to make adjustments before backups begin and ensures an orderly transition from one configuration to a nother.

Managing Backup Policies (Classes)
A NetBackup class defines the backup policy for a specific group of one or more clients. Every client must be in at least one class. The best approach is usually to divide clients into groups according to their backup and archiving requirements an d then co nfigure a cla ss for eac h group.
This chapter explains how to configure classes. The first two topics introduce classes and give guidelines for planning them. The remaining topics have detailed configuration instructions.

Introduction to NetBackup Classes
Parts of a Class Definition
There are four parts to a class definition:
• General Attributes
• Client List
• File List
• Schedules
General Attributes
Active
Class type
--------
--------------
Client List
File List
Schedules
General Attributes
The general attributes determine the basic characteristics of all the backups that NetBackup performs for the class. For example:
• Whether the class is active
• Class type (type of clients it can include)
• Priority that NetBa ckup gives to jobs in this class relative to other classes
• Storage un it and volume pool for backups of clients in this class. A storage unit or volume pool on the schedule, overrides the general attribute setting.
A complete list of general attributes is provided later in this chapter.
34
NetBackup System Administrator’s Guide - Windows NT Server
Page 65
Client List
The client list names the clients that belong to the class. NetBackup backs up these clients according to the file list, schedules, and general attributes for the class. NetBackup clients must be in at least one class and can be in more than one. Having a client in more than one class is useful, for example, to back up different sets of files according to different rules.
File List
The file list names the files and directories that NetBackup includes in automatic backups for clients in this class. The file list does not apply to user backups or archives because in those instances the user selects the files.
NetBackup uses the same file list for all clients in the class but all the files do not have to exist on all clients. NetBackup backs up the files that it finds. Files are processed serially for each client. It is possible, however, to back up more than one client in parallel.
3
A related item is the exclude list. Yo u can create this list on each client to specify files that you do not want to include in automatic backups of that client. The exclude list does not apply to user backups and archives.
Schedules
Schedules control the backups for the class. For example, there can be schedules for automatic-full, automatic-incremental (differential or cumulative), and user backups or archives. A class can have multiple schedules.
• Schedules for autom atic backups back up the file list on all clients in the class according to the timetables set up in the schedules.
• Schedules for user backups and archives specify when users can start these operations from the clients.
Each schedule also specifies other criteria, such as how long to retain the backups. A storage unit and volume pool can also be specified.

Example Classes
The following figure shows the clients, file list, and schedules for two example classes.
• Example class 1 specifies that files in
C:\ D:\Projects
be backed up for the clients named mars, jupiter, and neptune. This class has daily and weekly schedules. All backups go to 8-mm tape.
• Example class 2 has different scheduling requirements. One difference is that the monthly backups go to DLT tape. Example class 2 also has a schedule for user backups.

Planning Guidelines for Classes
Classes allow you to meet the needs of a wide variety of clients in a single NetBackup configuration. Taking full advantage of classes requires careful planning. The following procedure provides some planning guidelines.
1. Divide clients into groups according to the types of work they perform. Clients used for similar tasks usually have a high level of commonality in
their backup requirements. For example, most clients in an engineering department create the same types of files at similar levels of importance.
In some instances, you can create a class for each group and this will be adequate for defining your classes. In other cases, you will have to further subdivide the clients based on their backup requirements as explained in later this procedure.
The table below is the initial grouping for our example. We assume these clients are in same work group and the ini tial plan is to have them all in the same class.
Clients
mercury mars jupiter neptune pluto
2. Gather information abo ut each client. Include information relevant to the backups such as the names, size, and number of files.
38
NetBackup System Administrator’s Guide - Windows NT Server
Page 69
In our example client list, mercury is a server and has a large amount of data. To avoid excessively long backup times, we put mercury in a separate class called S1 and the workstations in a class called WS1. Later, we may find that we need more than one class to back up mercury, but w e will evaluate other factors first. For now, the classes are as follows:
Class Clients
S1 mercury (file server)
WS1 mars
jupiter (workstat ions) neptune pluto
3
3. Create classes to accommodate special storage requirements. The storage unit and volume pool settings apply to all files that are backed
up by the class. If files have special storage unit and volume pool requirements, create separa te cl asses f or the m, even if oth er fac tors, such a s schedules, are the same.
In our example (see below), we create a separate class (S2) for D:\h002\R&D and D:\h002\Desdoc on mercury because those files go on DLT tape. Other files on mercury go on 8 mm tape. If it is necessary to keep backups for some files on separate media, create a class that specifies a unique volume pool for those backups. Then, add the media for that volume pool as explained in the Media Manager Administrator ’s Guide - Windows NT Server.

4. Create additional classes if one set of sch edules does not accommodate all clients and files. Factors to consider are:
• Best times for backups to occur. To back up different clients on different
schedules, create more classes. For example, create different classes for night-shift and day-shift clients. In our example, we can back them all up during the same hours so no new classes are necessary.
• How frequently the files change. For example, if some files change very
infrequently in comparison to other files, back them up on a different schedule. To do this, create another class with an appropriate schedule and then assign the files and clients to that clas s.
In our example (see the table below), we place C:\ on mercury in a different class (S3). The C:\ drive on the workstations is also placed in a separate class (WS2).
• How long backups have to be retained. Each schedule ha s a retention
setting that determines how long NetBackup keeps files that are backed up by the schedule. Because the schedule backs up all the files in the file list, it is best if all files have similar retention requirements. Do not, for example, place files whose full backups must be retained forever in a class where full backups are retained for only a month.
In our example (see below), we place E:\h002\Desdoc on mercury in a different class (S4). This is done because E:\h002\Desdoc requires full backups every quarter and those backups must be retained for a much longer time than the other files on mercury.

5. Create separate classes for clients that require different general-attribute settings than other clients. Some general-attribute settings to consider are:
• Class type. There are several types of classes and you must place the
client in the correct type. For example, place Windows NT clients in an MS-Windows-NT class.
• Backup network drives. Select this attribute to back up files that the
client stores on network drives (applies only to MS-Window-NT classes).
Managing Backup Policies (Classes)
41
Page 72

• Class Priority. Use this attribute to control the order in which NetBackup
starts its backups. The client in the higher priority class is backed up first.
There are also other attributes that are explained later in this chapter. In our example, the general attributes are satisfactory for all clients and files so no extra classes are required.
6. Create separate classes as necessary to maximize the benefits of multiplexing.
Using multiplexing for slower clients that produce small backups is a strategy for maximizing drive utilization. However, higher-performance clients that produce long backups are likely to fully utilize drives and not benefit from multiplexing.
7. Evaluate total backup times for each schedule and further subdivide your classes to reduce backup times to an acceptable level.
Compute the approximate backup time by multiplying the speed of the device by the amount of data in the backup. For example, if your backup device transfers data at 800 kilobytes per second, it takes 0.7 hours to back up 2 gigabytes.
The variable that is easiest to control here is the amount of data in the backup. NetBackup imposes no limits on backup size, but try to keep backups to less than 2 gigabytes. In addition to reducing backup time, shorter backups mean usually mean less time to recover files that are near the end of the backup.
In our example, it so happens that backing up D:\User, D:\h001, and E:\h002\Projects on mercury takes too much time so we create a new class for E:\h002\Projects. This new class (S5) has the same requirements as S1 but we can now back up E:\h002\Projects separately thus reducing backup time. The table below shows the final set of classes.
In addition to reducing the backup time for each class, putting the files in separate classes can reduce the total backup time for the server mercury. NetBackup processes files within a file list serially and in the order they appear in the file list. However, separate classes are backed up in parallel if enough drives are available and the maximum jobs attributes are set to allow it (“Number of Concurrent Streams” on page 73 provides an explanation of maximum jobs settings that also applies to this discussion).
42
NetBackup System Administrator’s Guide - Windows NT Server
Page 73
Multiplexing and Allow Multiple Data Streams also allow backing up classes in parallel (see “Allow Multiple Data Streams” on page 70 and
“Multiplexing” on page 135). For best performance with multi ple data streams, use only one data stream to back up each physical device on the client. Multiple concurrent streams from a single physical device can adversely affect backup times.

Class Storage Unit
Specifies the default storage unit for backups of thi s class and NetBackup uses it for all schedules that do not specify another storage unit. A schedule-level storage unit (when specified) overrides the class default (see “Override Class
Storage Unit” on p age 107). To select the class storage unit, click the button to the right of the box to
display a selection list. Then, select either a specific storage unit or Any Available.
If you select Any Available, NetBackup tries storage units in alphabetical order and uses the first one that meets the following requirements:
• Is Not “ on demand only”
• Has available driv es
• H as media av ailable i n the required volume poo l
Example
Assume that all schedules but one can use a Tape Stacker 8MM. The schedule that is the exception requires a Tape Library DLT. Here, you specify Tape Stacker 8MM at the class level and specify the following on the schedules:
60
NetBackup System Administrator’s Guide - Windows NT Server
Page 91
• For schedules that can use the Tape Stacker 8MM, clear Override Class Storage Unit. When these schedules run, NetBackup uses a Tape Stacker 8MM.
• For the s chedule that requires DLT, select Override Class Storage Unit and select Tape Library DLT. Wh en this schedule runs, NetBackup overrides the class default and uses the DLT library.
Notes on Specifying a Storage Unit
• I f your site h as only one s torage unit o r there is no sp ecific preferen ce for storage, specify Any Available for the class storage unit and do not specify a storage unit at the schedule level.
When you specify Any Available for the class storage unit and do not specify one at the schedule level, ensure that at least one storage unit is configured to be not on demand only. Otherwise, NetBackup will be unable to find a storage unit for the backups.
3
• If you desig nate a specific storage unit and it is not available (for example, because it is down for maintenance), backups will not run for classes and schedules that require the storage unit.
• If your NetBackup con figuration has several storage units and you want a class to use more than one but not all of the storage units, perform the following:
• When you configure volumes in Media Manager, define a volume pool
and volumes that only the desired storage units can access.
• For the specific class, set Class Volume Pool to the volume pool that only
the desired storage units can access.
• For all classes, set Class Storage Unit to Any Available.
Class Volume Pool
Specifies the default volume pool for backups of th is class and NetBackup us es it for all schedules that do not specify another volume pool. A schedule-level volume pool (when specified) overrides the class default (explained later under “Override Class Volume Pool” on page 107). If you do not name a volume pool for either the class or the schedule, NetBackup uses the “NetBackup” pool.
Managing Backup Policies (Classes)
61
Page 92
3
To specify the class volume pool, click the button to the right of the box and select the desired volume pool name from the list. The list shows all previously configured volume pools. You can also type the name of the pool in the box and then configure it in Media Manager.
Example
Assume that you want all schedules but one to use the “backups” pool. The exception in this case is a user-archive schedule that requires the “archive” pool.
Here, set Class Volume Pool to “b ackups” When you set up the schedules for the class, set Override Class Vo lume Pool as follows:
• For schedules that use the “backups” volume pool, clear Override Class Volume Pool.
• For the schedule that requires the “archive” volume pool, select Override Class Volume Pool and then specify “archive” for the pool name.
Notes on V olume Pools
• This setting is optional for Media Manager type storage units and is n ot available for Disk type storage units.
• It is possible to co nfigure a scratch pool from which NetBackup can automatically transfer volumes when another volume pool ha s no media available. See the Media Manager System Administrator ’s Guide - Windows NT
Server for an explanati on of scratch pools.
Maximum Jobs per Class
Specifies the maximum number of concurrent jobs that NetBackup allow s for this class. To change the setting, click in the box and type a new value. You can leave this a ttribute a t the default (99), excep t when there a re enough devic es that the possible number of concurrent backups will affect performance.

Notes on Maximum Jobs Per Class
The number of concurrent backup jobs that NetB ackup can perform depen ds on:
• Number of storage d evices available. With tapes or optical disks, this depends on the total number of drives in the storage unit. With magnetic disk, the storage device is defined as a file path and the availa ble space and system capabilities determines the limit.
• Server speed. Too many concurrent backups interfere with the performance of the server. The actual number that is permissible depends on the hardware, operating system, and applications that are running.
• Network loading. The available ban dwidth of the network d etermines how many backups can occur concur rently. If yo u encounter loading problems, consider backing up over multiple networks or using compression (UNIX clients only).
A special case exists when backing up a client that is on the same machine as the server. Here, network loading is not a factor because you do not use the network. Client and server loading, however, is still a factor.
• Multiplexing . If you use multiplexing, set Maximum Jobs per Class high enough to support the specified level of multiplexing.
Lower val ues can li mit multi plexing wi thin a cla ss if there are job s from different schedules within that class. For example, if Maximum Jobs per Class is 2, NetBackup can never have more than two jobs running at a time for the class. If there are two jobs for schedule A and two jobs for schedule B, only one schedule can run at a time, regardless of multiplexing settings.
Managing Backup Policies (Classes)
63
Page 94
3
For more information on multiplexing, see (See “Multiplexing” on page 135. )
• Maximum Jobs per Class does not prevent concurrent jobs if the jobs are from different cl asses.
For example , if there are three classes and each has its M aximum J obs per Class at 2, NetBackup can start two jobs from each class and have a total of six running at one time.
Job Priority
Specifies the priority that NetBackup assigns to automatic-backup jobs for this class. When a drive becomes available, NetBackup assigns it to the first client in the highest priority class. For an explanation of all the factors involved in establishing backup priority, see “Automatic-Backup Scheduling” on page 426.
To set the priority, type any positive integer in the Job Priority text box. Higher values have higher priority. The default is 0.
Keyword Phrase (optional)
Specifies a keyword phrase that NetBackup will associate with all backups or archives for this class. Users on Windows NT and UNIX clients can then optionally list or restore only the backups that have this phrase associated with them (see the appropriate NetBackup user ’s guide). The user interfaces on other NetBackup clients do not support keyword phrases.
You can use the same keyword phrase for more than one class. This makes it possible to link backups from related classes. For example, you can use one keyword phrase for full backups and another for incremental backups.
The phrase can be a maximum of 128 characters in length. All printable character s are permitt ed includ ing spac es and peri ods. By d efault, th ere is no keyword phrase.
Users on Windows NT and UNIX clients can also specify a keywo rd phrase for a user backup or archive. A user phrase overrides the class phrase.

To activate the class, select the box. The class must be active for NetBackup to execute automatic-backup schedules or allow user backups or archives.
Leaving a class inactive is useful if there are problems and you want to suspend backups until they are resolved. It is also useful if you are creating new classes but cannot complete them right away.
Backup Network Drives
Note: The Backup Network Drives attribute applies only to Windows NT
clients that are in an MS-Windows-NT type class.
Specifies that you want NetBackup to back up or archive files that are on network drives and are named in the file list (or by the user in the case of a user backup). With this attribute selected, NetBackup also backs up CD-ROM drives on Windows NT systems. Clear the box to prevent the backup or archive of network drives or backup of CD -ROM drives.

True Image Restore Information
Note: The True Image Restore Information attribute applies only to Standard,
MS-Windows-NT, OS/2, SAP, and NetWare classes.
Specifies that NetBackup will start collecting the information required to restore directories to contain what they had at the time of any selected full or incremental backup. Files that were deleted before that time are not restored. For incremental backups, true-image restores also do not include files that were moved, renamed, or newly installed in the directories, unless you also select With Move Detection.
NetBackup starts collecting the true-image restore information beginning with the next full or incremental backup for the class. Users can then perform true­image restores of directories that were in the backups.
The true-image restore information is collected for each client regardless of whether any files were a ctually changed.

With Move Detection
Specifies that NetBackup also collect the information required to detect files and directories that have been moved, renamed, or newly installed and then include those files and directories in incremental backups for this class.
NetBackup accomplishes move detection by comparing path names with tho se from the previous full or incremental backup. If a name is new or changed, the file or directory is backed up. Without move detection, only archive bits are considered.
The followin g are exampl es of move de tection:
• A file named C:\pub\doc is moved to or installed in C:\spec\doc. Here, the archive bit is unchanged but C:\spec\doc is new in the C:\spec\ directory and is backed up.
• A directory na med C:\security\dev\ is renamed as
C:\security\devices\. Here, the archive bit is unchanged but C:\security\devices\ is a new directory and is backed up.
NetBackup starts collecting information required for move detection beginning with the next full or incremental backup for the class. This first backup after setting the attribute, always backs up all files, even if it is an incremental. Move detection takes space on the client and the backup can fail if there is not enough disk space available.
Example of a T rue-Ima ge Restore
The following table shows the contents of the C:\home\abc\doc directory during a series of backups between 12/01/1995 and 12/04/1995.

12/04/1995 Incremental file1 file2 ------------- ------------- ------ ------------- file4
Note: dashes ( ------ ) mean that the file was deleted prior to this backup.
Backup Files Backed Up in C:\user\doc
Assume that you are going to restore the 12/04/1995 version of the C:\user\doc director y.
• If you do a regular rest ore, the restored directory has all files and directories that ever existed in C:\user\doc from 12/01/1995 (last full backup) through 12/04/1995:
file1 file2 dirA\fileA dirB\fileB file3 dirC\fileC file4
• If you do a true-image restore of the 12/04/1995 backup, the restored directory has only the files and directories that existed at the time of the incremental backup on 12/04/1995:
file1 file2 file4

NetBackup does not res tore any of the files deleted prior to the 12/04/1995 incremental backup.
The restored directory does not include the dirA and dirC subdirectories, even though they were backed up on 12/04/1995 with a user back up. NetBackup did not restore these directories because they did not exist at the time of the incremental backup that was the reference for the true-image rest ore .
Also, NetBackup does not provide true-image restores based on the time of a user backup or archive. It does, however, use the backups from user operations for a true-image restore, if they are more recent than the latest automatic full or incremental.
Notes On T rue-Image Restores and Move Detection
• Because the additional information that NetBackup collects for incrementals is the same as for a full backup, incremental backups take much more disk space when you are collecting true-image restore information. Adding move detection requires even more additional space.
• You can set the period of time that NetBackup keeps the true-image restore information by using the How Long to Keep TIR Info rmation global attribute. See “How Long to Keep TIR Information” on page 473.
• Incremental backups are slower for a class where true-image restore information is being collected.
• You can perform true-image restores only on directories that were backed up by a class for which NetBackup is collecting true-image restore information.
If you intend to restore an entire file system or disk by using a true-image restore, ensure that all the desired directories are backed up by a class that is collecting true-image restore information.
• For true-image restores, you can list and select only directories. In true-image restore mode, the client-user interface does not show
individual files or let you select them. Th e NetBackup user’s guides explain this further and provide instructions for performing true-image restores.

• A true-image restore preserves files that are currently in the directory but were not present when the backup was done. In our previous example, assume you created a file named file5 after the incremental backup occurred on 12/04/1995, but before doing the restore. In this case, the contents of the directory after the restore is:
file1 file2 file4 file5
Follow NFS
Note: The Follow NFS attribute applies only to UNIX clients in Standard or
SAP classes.
3
Specifies that you want NetBackup to back up or archive any NFS mounted files that are named in the file list (or by the user in the case of a user backup or archive). Clear the box to prevent the back up or archive of NFS mounted files.
Cross Mount Points
Note: The Cross Mount Points attribute applies only to UNIX clients in
Standard, SAP, or NDMP cla sses.
Controls whether NetBackup crosses file system boundaries during a backup or archive on UNIX clients.
Compression
Note: Compression applies only to UNIX clients in Standard or SAP classes.
Specifies software compression for backups of this class. Select the box to enable compression (the default is no compression). For more information on using this attribute, see the NetBackup for Windows NT - UNIX Supplement.

Encryption
Note: Ava ilable only when the NetBackup Encryption option is installed and
configured. Se e the NetBackup Encryption System Administrator’s Guide.
Specifies encryption for backups of clients in this class.
Individual File Restore From Raw
Note: The Individual File Restore From Raw class attribute applies only to
UNIX clients in Auspex FastBackup and FlashBackup type classes. See the NetBackup System Administrator’s Guide - UNIX for more information on Auspex FastBackup. For FlashBackup, see the NetBackup FlashBackup System Administrator ’s Guide.
Controls whether NetBackup can restore individual files from full or incremental raw-partition backups that are performed for clients in this class. If you select this box, NetBackup starts saving the information necessary to restore individual files from raw-partition backups that are subsequently performed.
Block Level Incremental
Note: Ava ilable with VERITAS Oracle Edition.
Specifies block-level-incremental backups for clients in this class.
Allow Multiple Data Streams
Specifies that an automatic backup schedule for this class can start multiple backups for each client according to the directives that are specified in the file list.
• The number of backups tha t are started is determined by the directives in the file list (see “File-List Directives for Multiple Data Streams” on pag e 94) .
