Chapter 1. Introduction
1.1 Acronis® True Image Echo Server – a complete solution for corporate users
You have come to rely on your servers to run your business and retain key enterprise
data. Acronis True Image Echo Server provides comprehensive, reliable, and costeffective system protection and recovery for corporate servers, running Linux. With
Acronis True Image Echo Server you have peace of mind knowing you are protected and
can recover from any situation.
Minimizes downtime
Acronis True Image Echo Server for Linux enables you to restore systems in minutes, not
hours or days. An entire system can be restored from an image that includes eve rything
the system needs to run: the operating system, applications, databases, and
configurations. No reinstallation or reconfiguration is required. Moreover, complete system
restoration can be performed to an existing system or to a new system with different
hardware or to virtual machines. File-based backups provide you with the flexibility to
only backup selected critical files.
Eases Administration
Wizards guide users through backup and recovery tasks, ensuring the product can be
implemented with minimal user training.
Automates Backup
With the scheduling capability in Acronis True Image Echo Server, you simply create
backup tasks, tailored by group, at certain times or at certain events, automating
backups.
To ensure that backups have occurred, or user intervention is required, you can request
notifications via email or pop-up. You can view events in Acronis own log.
The product also supports the creation of custom comman ds before and after backups.
For example, users can automatically run anti-virus products before an image is created
and verify the validity of backups after they have been created.
Ensures 24 X 7 Uptime
With the Acronis Drive Snapshot systems can be imaged while they are in use, supporting
24 by 7 availability. This technology enables the product to backup and image critical
operating system files, the master boot record and any partition-based boot records
without requiring a reboot. A CPU allocation feature allows you to limit the amount of CPU
usage for the application to maximize the CPUs available for mission critical applications.
Moreover, users can control hard disk drive writing speeds and control network bandwidth
used during backups, allowing you minimally disrupt business operations.
For correct backup of mission critical databases, Acronis True Image Echo Server will
execute your custom commands, that suspend and resume database processing, before
and after data capture.
Supports Cutting Edge Technology
Businesses today are moving to leverage the latest technologies, dual-core 64 bit
processors and 64 bit operating systems. With Acronis True Im age Echo Server, you can
protect these new machines, as well as legacy ones, running one solution.
Leverages Existing Technology Investments
The product can leverage your current storage infrastructure by suppor ting a wide variet y
of storage media, so you can avoid costly hardware pur chases to implement the solution .
The product supports key storage technologies such as: Direct Attached Storage ( DAS),
Network Attached Storage (NAS), Storage Area Networks (SAN), Redundant Arrays of
Independent Disks (RAID) devices, tapes, USB and IEEE-1394 (FireWire) compliant
storage devices, CDs, removable drives (Floppy, Zip, etc.) and shared storage. Mor eover,
the product ensures that you maximize the space on these reso urces with four levels of
compression.
Disk cloning and new disk deployment
Acronis True Image Echo Server can be used to clone an im age onto m ultiple serve rs. Fo r
example, a company purchased several servers and needs similar environments on each
of them. Traditionally, an IT manager should install the operating system and programs
on every server. With Acronis True Image Echo Server, the IT manager can creat e a disk
image of the first system deployed. That image can then be duplicated onto multiple
servers.
If you need to upgrade the server hard disk drive, Acronis True Image Echo Server
simplifies the task to few mouse clicks creating the exact copy of your old disk to a new
one and adjusting partitions size to fit a new hard disk.

Chapter 3. General information and proprietary Acronis technologies
3.1 The difference between file archives and disk/partition images
A backup archive is a file or a group of files (also called in this guide “backups”), that
contains a copy of selected files/folders data or a copy of all information stored on
selected disks/partitions.
When you back up files and folders, only the data, along with the folder tree, is
compressed and stored.
Backing up disks and partitions is performed in a different way: Acronis True Image Echo
Server saves a sector-based snapshot of the disk, which includes th e operating system,
registry, drivers, software applications and data files, as well as system areas hidden from
the user. This procedure is called “creating a disk image,” and the resulting backup
archive is often called a disk/partition image.
Acronis True Image Echo Server stores only those hard disk parts that contain data (for
supported file systems). This reduces image size and speeds up image creation and
restoration.
A partition image includes all files and folders independent of their attributes (including
hidden and system files), a boot record and file system super block.
A disk image includes images of all disk partitions as well as the zero track with master
boot record (MBR).
By default, files in all Acronis True Image Echo Server archives have a “.tib” extension.
It is important to note that you can restore files and folders not only from file archives,
but from disk/partition images, too. To do so, mount the image (see
partition images
files or folders.
) or start the restore wizard, select image and select Restore specified
10.2 Mounting
3.2 Full, incremental and differential backups
Acronis True Image Echo Server can create full, incremental and differential backups.
A full backup contains all data at the moment of backup creation. It forms a base for
further incremental or differential backup or is used as a standalone archive. A full backup
has the shortest restore time as compared to incremental or differential ones.
An incremental backup only contains data changed since the last full or incremental
backup creation. Therefore, it is smaller and takes less time to create. But as it doesn’t
contain all data, all the previous incremental backups and the initial full backup are
required for restoration.
Unlike incremental backup, when every backup procedure creates the next file in a
“chain,” a differential backup creates an independent file, containing all changes
against the initial full archive. Generally, data from a differential backup will be restored
faster than an incremental one, as it does not have to process through a long chain of
previous backups.
Copyright © Acronis, Inc., 2000-2008
A standalone full backup may be an optimal solution if you often roll back the system to
the initial state (like in a gaming club or Internet café, to undo changes made by the
guests). In this case, you need not re-create the initial full image, so the backup time is
not crucial, and the restore time will be minimal.
Alternatively, if you are interested in saving only the last data state to be able to restore it
in case of system failure, consider the differential backup . It is particularly effective if your
data changes tend to be little as compared to the full data volume.
The same is true for incremental backup. In addition, it is most useful when you need
frequent backups and possibility to roll back to any of stored states. Having created a full
backup once, if you then create an incremental backup each day of a month, you will get
the same result as if you created full backups every day. However, the cost in time and
disk space (or removable media usage) will be as little as one tenth as much.
It is important to note that the above arguments are nothing but examples for your
information. Feel free to make up your own backup policy in accordance with your specific
tasks and conditions. Acronis True Image Echo Server is flexible enough to meet any reallife demands.
An incremental or differential backup created after a disk is defragmented might be
considerably larger than usual. This is because the defragmentation program changes file
locations on disk and the backups reflect these changes. Therefore, it is recommended
that you re-create a full backup after disk defragmentation.
3.3 Acronis Secure Zone®
The Acronis Secure Zone is a special partition for storing archives on the computer system
itself. In the Acronis True Image Echo Server Wizards’ windows the zone is listed along
with all partitions available for storing archives.
Acronis Secure Zone is always available for archive creation as long as there is space for
the backup file. If there is not enough space, older archives will be deleted to create
space.
Acronis True Image Echo Server uses the following scheme to clean up Acronis Secure
Zone:
• If there is not enough free space in the zone t o create a backup, the pro gram deletes
the oldest full backup with all subsequent incremental/differential backups.
• If there is only one full backup (with subsequent incremental/differ ential backups) left
and a full backup is in progress, then the old full backup and incremental/differential
backups are deleted.
• Otherwise, (only one full backup left, and an incremental/differential backup is in
progress) you will get a message about space error. In that case you will have to
either re-create the full backup or increase Acronis Secure Zone.
Thus, you can back up data automatically on a schedule (see
), and not worry about the zone overflow issu es. How ever , if you keep long chains of
tasks
incremental backups, it will be a good practice to periodically check the zone free space,
indicated on the second page of the Manage Acronis Secure Zone wizard.
Chapter 7. Scheduling
For information on how to create, resize or delete Acronis Secure Zone using this wizard,
Chapter 8. Managing Acronis Secure Zone
see
.
In case you remove Acronis True Image Echo Server from the system, there is an option
to keep Acronis Secure Zone along with its contents (which will enable data recovery on
booting from bootable media) or remove Acronis Secure Zone.
The Acronis Secure Zone should not be the only location where a backup is stored.
Should the disk have a physical failure, the Acronis Secure Zone could be lost. This is
particularly critical for backups of servers; the Acronis Secure Zone should only be one
part of an overall backup strategy.
3.4 Working from a rescue CD
In some situations (e.g. if the operating system fails to boot, or when cloning a mounted
disk), you might have to work with Acronis True Image Echo Server without loading the
OS. In those cases, you can use the Acronis rescue CD. It is highly recommended that
you create it as described in
Chapter 9. Creating bootable media
.
3.5 Working from a remote terminal
You can control the image creation or restorati on process remotely from any computer in
the local network or Internet, operating under Windows, Mac OS or any UNIX clone.
To act as a remote terminal, this computer must have X Server software installed. Start
the X Server and log on to the server using SSH-enabled software. For example, Putty is
one of the most popular Windows programs of that type.
Then you can invoke Acronis True Image Echo Server GUI with the trueimage command
or use the trueimagecmd command line tool.
3.6 Backing up software and hardware RAID arrays
Acronis True Image Echo Server supports software and hardware RAID arrays as if these
were simple single hard drives. However, as such arrays have a structur e different from
typical hard disks, there are peculiarities affecting the way data is stored.
Software RAID arrays under Linux OS combine several hard disks partitions and mak e
solid block devices (/dev/md0, ... /dev/md31), information of which is stored in
/etc/raidtab or in dedicated areas of that partitions. Acronis True Image Echo Server
enables you to create images of active (mounted) software arrays similar to typical hard
disk images.
Partitions that are part of software arrays are listed alongside other available partitions as
if they had a corrupted file system or without a file system at all. There’s no sense in
creating images of such partitions when a software array is mounted, as it won’t be
possible to restore them.
Parameters of software disk arrays are not stored in images, so they can only be restored
to a normal partition, or unallocated space, or previously configured array.
Operating from a rescue CD, Acronis True Image Echo Server tries to access parameters
of a software disk array and configure it. However, if the necessary information is lost,
the array cannot be configured automatically. In this case, create a software array
manually and restart the restoration procedure.
Hardware RAID arrays under Linux combine several physical drives to cr eate a single
partitionable disk (block device). The special file related to a hardware disk array is
usually located in /dev/ataraid. Acronis True Image Echo Server enables you to create
images of hardware disk arrays similar to images of typical disks and partitions.
Copyright © Acronis, Inc., 2000-2008
Physical drives that are part of hardware disk arrays are listed alongside other available
drives as if they had a bad partition table or no partition table at all. There’s no sense in
creating images of such drives, as it won’t be possible to restore them.
3.7 Support for LVM volumes
When running in Linux environment with 2.6.x kernel, Acronis True Image Echo Server
supports disks, managed by Logical Volume Manager (LVM). You can back up da ta of one
or more LVM volumes and restore it to a previously created LVM volume or MBR disk
(partition), likewise it is also possible to restore MBR volume data to an LVM volume. In
each case, the program stores and restores volume contents only. The type or other
properties of the target volume will not be changed.
A system, restored from an LVM volume image over an MBR disk, cannot boot because
its kernel tries to mount the root file system at the LVM volume. To boot the system,
change the loader configuration and /etc/fstab so that LVM is not used. Then reactivate
your boot manager as described in section 6.3.11.
When restoring an LVM volume over an MBR partition, resizing of the partition is possible.
LVM volumes appear at the end of the list of hard disks available for backup. Hard disk
partitions included in LVM volumes are also shown in the list with None in the Type
column. If you select to back up such partitions, the program will image it sector-bysector. Normally it is not needed. To back up all available disks, specify all dynamic
volumes plus partitions not belonging to them.
The following is an example of a list of drives obtained with the --list command (GUI
wizards display a similar table). The system has three physical disks (1, 2, 3). Two
dynamic volumes 4-1 and 4-2 are arranged across partitions 1-2 and 2-1. Hard drive 3
includes Acronis Secure Zone which is not normally imaged.
Num Partition Flags Start Size Type
------------------------------------- ---------- ---------- -----------
Disk 1:
1-1 hda1 (/boot) Pri,Act 63 208782 Ext3
1-2 hda2 Pri 208845 8177085 None
Disk 2:
2-1 hdb1 Pri,Act 63 8385867 None
Disk 3:
3-1 hdd1 Pri,Act 63 1219617 Ext3
3-2 Acronis Secure Zone Pri 1219680 2974608 FAT32
Dynamic Volumes:
4-1 VolGroup00-LogVol00 15269888 Ext3
4-2 VolGroup00-LogVol01 1048576 Linux Swap
To image dynamic volume 4-1, select partition 4-1.
To image all three physical drives, select partitions 1-1, 3-1, 4-1, 4-2.
If you select disk 2, partition 1-2 or 2-1, the program will create a sector-by-sector copy.
3.8 Backing up to tape drive
Acronis True Image Echo Server supports SCSI tape drives. It can store backups on the
tape and restore data from the tape, store large backups to multiple tapes, and append
incremental/differential changes to a tape with the existing archives.
If a SCSI tape drive is connected to the server, the list of devices available for storing
backups will be extended with a name corresponding to the drive type.
Backup and restore using tape drive proceed in the same way as wi th other devices, with
the following exceptions.
1. A full backup can be stored on an empty tape only. If the tape already contains data,
its contents will be overwritten on prompt. You have an option to disable prompts. See
details in
5.3.11 Additional settings
2. In case you want to keep more than one archive on the ta pe, for example, back up two
disks separately, choose
incremental
create an initial backup for the second disk. In other situations, incremental backup is
used for appending changes to the previously created archive.

describes the selected property in detail. The disk information includes its physical
parameters (connection type, device type, size, etc.); partition information includes both
physical (sectors, location, etc.), and logical (file system, free space etc.) parameters.
You can change the width of a column by dragging its borders with the mouse.
Chapter 5. Creating backup archives
To be able to restore the lost data or roll back your system t o a predetermined state, you
should first create a data or entire-system backup file.
If you are not concerned about restoration of your operating system along with all
settings and applications, but plan to keep safe only certain data (the current project, for
example), choose file/folder backup. This will reduce the archive size, thus saving disk
space and possibly reducing removable media costs.
Backing up the entire system disk (creating a disk image) takes more disk space but
enables you to restore the system in minutes in case of severe data damage or hardware
failure. Moreover, the imaging procedure is much faster than copying files, and may
significantly speed the backup process when it comes to backing up large volumes of data
(see details in
This chapter describes creating backup archives using Acronis True Image Echo Server
GUI under X Window System. See
service.

).
1. Start the Create Backup Wizard by clicking on the backup operation icon in the main
program window.
2. Select My Data.
3. From the tree pane, select files and folders to back up. You can select a random set of
files, folders, partitions, disks and even computers.
In order to restore your operating system, you must image the system disk or partition; a
file-based backup is not sufficient for the operating system restore.
4. Set filters for the specific types of files you do not wish to back up. For example, you
may want hidden and system files and folders not to be stored in the archive.
Copyright © Acronis, Inc., 2000-2008
You can also apply custom filters, using the common masking rules. For example, to
exclude all files with extension .tib, add *.tib mask. My???.tib mask will reject all .tib
files with names consisting of five symbols and starting with “my ”.
All of these settings will take effect for the current task. For information on how to set the
default filters that will be called each time you create a file backup task, see
files exclusion.
5.3.2 Source
5. Select the name and location of the archive.
If you are going to create a full backup, type the file name in the File Name line, or use
the file name generator (a button to the right of the line). If you select an existing full
backup, it will be overwritten.
Including [date] in the backup file name will add to the name the time and date of the
backup creation formatted as <DD-Month-YYYY HH:MM:SS>. Example:
C:\MyBackup[date].tib.
If you are going to create an incremental backup (see
differential backup
In fact, if all incremental backup files are stored together with the basic full backup, it
doesn't matter which one you select, as the program will recognize them as a single
archive. If you stored the files on several removable disks, you must provide the latest
archive file; otherwise, restoration problems might occur.
), select the latest full or incremental backup you have.
3.2 Full, incremental and
If you are going to create a differential backup, select the full backup which will be a
base, or any of the existing differential backups. Either way, the program will create a
new differential backup.
The “farther” you store the archive from the original folders, the safer it will be in case of
data damage. For example, saving the archive to another hard disk will protect your data
if the primary disk is damaged. Data saved to a network disk, ftp-server or removable
media will survive even if all your local hard disks are down. In addition to NFS, Acronis
True Image Echo Server supports the SMBFS network file system.
Please check, that the network backup node is accessible for Acronis True Image Echo
Server Rescue CD Network Browser, otherwise you cannot restore images stored on this
node.
See notes and recommendations for using the FTP server in
media.
1.4.2 Supported storage
6. Select whether you want to create a full, incremental or differential backup. If you have
not backed up the selected files/folders yet, or the full archive seems too old to append
incremental changes to it, choose full backup. Otherwise it is recommended that you
create an incremental or differential backup (see
backup
).
3.2 Full, incremental and differential
Copyright © Acronis, Inc., 2000-2008
7. Select the backup options (that is, backup file splitting, compression level, password
protection, pre/post backup commands etc.). You may Use default options or Set the
options manually. If the latter is the case, the settings will be applied only to the
current backup task. Alternatively, you can edit the default options from the current
screen. Then your settings will be saved as the defaults. See
5.3 Setting backup options
for more information.
8. Provide a comment for the archive. This can help prevent you from restoring the wrong
files. However, you can choose not to make any notes. The backup file size and creation
date are automatically appended to the description, so you do not need to enter this
information.
9. At the final step, the backup task summary is displayed. Up to this point, you can click
Back to make changes in the created task. Clicking Proceed will launch the task
execution.
10. The task progress will be shown in a special window. You can stop the procedure by
clicking Cancel.
You can also close the progress window by clicking Hide. The backup creation will
continue, but you will be able to start another operation or close the main program
window. In the latter case, the program will continue working in the background and will
automatically close once the backup archive is ready. If you prepare some more backup
operations, they will be queued after the current one.
