S.M.A.R.T. Information

Item Description

Tray Number Tray the hard disk is installed in. Model Model name of the installed hard disk. Power ON Hours Count of hours in power-on state. The raw value of this attribute shows total count of hours (or min-

utes, or seconds, depending on manufacturer) in power-on state. Temperature Celsius The current temperature of the hard disk in degrees Celsius. Reallocated Sector Count Count of reallocated sectors. When the hard drive ﬁnds a read/write/veriﬁcation error, it marks this sec-

tor as "reallocated" and transfers data to a special reserved area (spare area).

This process is also known as remapping and "reallocated" sectors are called remaps. This is why, on a

modern hard disks, you cannot see "bad blocks" while testing the surface - all bad blocks are hidden in

reallocated sectors. However, the more sectors that are reallocated, the more a decrease (up to 10% or

more) can be noticed in disk read/write speeds.

Chapter 3: System Administration

Current Pending Sector

Current count of unstable sectors (waiting for remapping). The raw value of this attribute indicates the

total number of sectors waiting for remapping. Later, when some of these sectors are read successfully,

the value is decreased. If errors still occur when reading sectors, the hard drive will try to restore the

data, transfer it to the reserved disk area (spare area), and mark this sector as remapped. If this attribute

value remains at zero, it indicates that the quality of the corresponding surface area is low. Test Type Set short or long time to test.

Test Result Result of the test. Tes t T im e Total time of the test.

Bad Block Scan•

If this RAID volume is meant to be the Master RAID volume, tick the Master RAID checkbox.4.

In a multiple RAID conguration, one RAID volume must be designated as the Master RAID volume. The Master RAID volume will store all installed modules. If the Master RAID is changed to another location (i.e. assigning volume 2 to be the Master RAID volume after volume 1 had been previously assigned), then all modules must be reinstalled. In addition, all system folders that were contained on the Master RAID volume will be invisible. Reassigning this volume to be the Master RAID will make these folders visible again.

Selected whether the RAID volume will be encrypted or not. 5. The RAID volume can protect data by using RAID Volume Encryption function to prevent the risk of data exposure. To activate this function, the Encryption option needs to be en-data exposure.

RAID Levels

Level Description

JBOD The storage volume is a single HDD with no RAID support. JBOD requires a minimum of 1 disk. RAID 0 Provides data striping but no redundancy. Improves performance but not data safety. RAID 0 requires a minimum of

2 disks.

RAID 1 Oﬀers disk mirroring. Provides twice the read rate of a single disk, but same write rate. RAID 1 requires a minimum of

2 disks.

RAID 5 Data striping and stripe error correction information provided. RAID 5 requires a minimum of 3 disks. RAID 5 can sus-

tain one failed disk.

RAID 6 Two independent parity computations must be used in order to provide protection against double disk failure. Two

diﬀerent algorithms are employed to achieve this purpose. RAID 6 requires a minimum of 4 disks. RAID 6 can sustain two failed disks.

RAID 10 RAID 10 has high reliability and high performance. RAID 10 is implemented as a striped array whose segments are

RAID 1 arrays. It has the fault tolerance of RAID 1 and the performance of RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two failed disks.

There are 3 available options for the user to operate Thecus IP storage associated with iSCSI setting. The details are listed in the following screenshot. If the options are modiﬁed, the system will need to reboot for the changes to take place.

iSCSI CRC/Checksum

To enable this option, the initiator can connect with “Data digest” and “Header digest”.

Max Connections

The maximum number of iSCSI connections.

Chapter 3: System Administration

Error Recovery Level

The Error Recovery Level (ERL) is negotiated during a leading iSCSI connection login in traditional iSCSI (RFC 3720) and iSER (RFC 5046).

ERL=0: Session Recovery

ERL=0 (Session Recovery) is triggered when failures within a command, within a connection, and/or within TCP occur. This causes all of the previous connections from the failed session to be restarted on a new session by sending a iSCSI Login Request with a zero TSIHRestart all iSCSI connections on any failure.

ERL=1: Digest Failure Recovery

ERL=1, only applies to traditional iSCSI. For iSCSI/SCTP (which has its own CRC32C) and both types of iSER (so far), handling header and data checksum recovery can be disabled.

ERL=2: Connection Recovery

ERL=2, allows for both single and multiple communication path sessions within a iSCSI Nexus (and hence the SCSI Nexus) to actively perform realligence/retry on iSCSI ITTs from failed iSCSI connections. ERL=2 allows iSCSI fabrics to take advantage of recovery in all regards of transport level fabric failures, and in a completely OS independent fashion (i.e. below the host OS storage stack).

When it comes to backing up your data, it’s very important to have ﬂexibility. Data guard provides you with many options, including full backup for all shares, custom backup for selected shares and iSCSI volume backup. Being based on the Linux operating system, it is also much more stable and experiences much less frequent data loss during transfer than other remote backup systems.

-For this tutorial you will need to use Rsync Target Server (Step 1) and Data Guard (Step 2+3) under Backup for this client/server backup feature. It also can be named for function “Remote Replication”.

Step 1 – Enabling Rsync on your target (backup) NAS

-Log in to your target (backup) NAS through the UI in your web browser

-Go to Rsync Target Server under Backup in the menu of the UI

Chapter 3: System Administration

Enable Rsync Target Server1.

Add a username and password (they can be diﬀerent than your NAS’s username and 2. password)

Select Apply3.

You will need this user name and password while the data is going to remotely backup to this Rsync target server.

Now Rsync is turned on your NAS, which means it can be used as a target for Rsync backup, in other words, only the backup NAS needs to be activated in this way.

Data Guard (Remote Backup)3.8.2

Step 2 – Setting up your backup task and schedule on your source NAS

-Log in to your other NAS (your source NAS) through the UI in your web browser

on the target system. Resume Partial File Handle Sparse File Try to handle sparse ﬁle eﬃciently so they take up less space on the destination. Keep ACL Setting It will backup not just data itself but also ACL conﬁguration with associated folders/

ﬁles.

Log Location

Choose the folder to save the log details while the task is executed.

Speed Limit

Input the bandwidth control for data backup operation.

Timeout Limit

Setup the timeout when trying to build up a connection in between the source and

the target system.

Enable Schedule

If backup is set as “Schedule”, please input the related period and time.

After the required ﬁelds are ﬁlled and the parameters are setup, click ‘Finish” to complete. The data guard task will appear in the list as shown below.

Chapter 3: System Administration

From the task list, you can now see the newly added task “fullback01”. The backup is setup as “real time”. From the status ﬁeld, “Processing” can be read as the back-up is performed on the ﬂy.

Custom Backup•

The custom backup setting is similar to the full backup. The only diﬀerences are explained below:

Inputs the share folder name of target sever where the source is going to backup. The sub-1. folder can be left as blank.

Select the source share folder(s) which are desired to be backed up to the target server. You 2. can also click on “Select All” from top right corner check box.

Chapter 3: System Administration

Click “Next” and more setting appears. These are the as the settings for “Full backup”3.

Click “Finish” and the data guard task will appear in the list as shown below.4.

From the task list, you can now see the newly added “customback01”. This backup is setup as “schedule”.

Chapter 3: System Administration

iSCSI Backup•

If the source unit contains iSCSI volume, it can be backed up to the target unit as a single ﬁle. The procedure is the same as for the previous “Full backup” and “Custom backup”, select “iSCSI backup” from data guard wizard.

Inputs the share folder name of the target sever where the source is going to backup. The 1. sub-folder can be left as blank.

Select the iSCSI target volume which you wish to back up to the target server.2.

Click “Next” and more settings will appear. It is slightly diﬀering from “Full backup” and “Custom 3. backup”. Only “Schedule” backup is supported with less options.

Chapter 3: System Administration

4. Click “Finish” and the data guard task will appear in the list as shown below.

From the task list, you can now see the newly added “iscsiback”. This backup is setup as “schedule”.

The source folder name will use iSCSI_+target volume name. So here it is displayed as “iSCSI_pmtest”. pmtest is the iSCSI target name when the iSCSI target was created.

The iSCSI backup can see the result as below. The task “iSCSI_pmtest” has backup to target

172.16.66.131 and share folder NAS_Public with ﬁle “iSCSI_pmtest”.

Restore•

To restore a backup from the backup task, simply select a task from the task list then click “Restore” from the function bar. The restore task will start to have the associated ﬁles/folders from the target server restored to the source.

Restore NAS Conguration•

This is a useful feature if the system conﬁguration needs to be restored to a brand new unit. Let ’s go thru the following example to see how it works.

The original source system has 3 RAID volume, “RAID”, ‘RAID10” and “RAID20”, and has backed up the system conﬁgurations to the target server.

The brand new source unit only has a 1 RAID volume ‘RAID”.

When adding a new backup task with “Full backup” or “Custom backup” and enabling the 1. option “Backup NAS Conﬁg” as shows below, the source unit system conﬁgurations are then backed up to the designed path on the target system every time the task is executed.

Click on “Restore NAS Conﬁguration” and the screen shown below will appear. Input the 2. target server ’s IP address where the system conﬁguration has been backed up, and necessary authentication info. Conﬁrm by doing a “Connection Test” to make sure the communication between the source and the target server works.

Chapter 3: System Administration

Click “Next” and a screen will appear as shown below. It has the listed available system 3. conﬁguration backup ﬁles. Select the one you want and click next. You also have the option to download the current system conﬁguration before restoring from the backup ﬁle.

After clicking “Next”, a screen will appear as shown below. Listed on the left hand side, you 4. will see the conﬁguration backup details which contain the 3 RAID volumes. On the right hand side, you will see a list of single “ RA I D ” volume. You may roll back to previous page to recall the example we have taken.

Chapter 3: System Administration

The backup conﬁguration has diﬀerent numbers of RAID volume than the current system (3 5. vs 1). It can be kept as the RAID volume mapping arranged by the system, then carry on to click “Finish”. This means that all 3 RAID volumes conﬁguration such as share folder etc. will all restore to the current unit in the RAID volume “RAID”.

In other circumstances, if the current unit contains 2 RAID volumes, then it can be chosen 6. from the left hand side of system backup conﬁguration RAID volume list which RAID volume to map to the current system.

Let’s see the following screen to make it clearer.

The current system has 2 RAID volumes, “RAID” and “RAIDa”. Select the RAID volume from the backup conﬁguration volume list which is going to be mapped to the RAID volume of the current system. Simply click on the right hand side of “RAIDa” and a drop down list will appear. Now you can choose which volume to map with. In this case the “RAID01” volume from the system backup conﬁguration will be mapped to the volume “RAIDa” of the current unit. Once again, it means all the shares that were created in the volume “RAID01” will be restored to volume “RAIDa” of the current system.

Item Description

Import This is associated with external devices which are added to the system such as USB disk. You can select a

folder from an external device and import it to the NAS as a share folder.

Copy Copy folder to folder or NAS folder to external device or external device to NAS folder. This backup is within

folder level.

Realtime Backup The task will be executed on the ﬂy between the source and the target. In other word, any changes made

at the source will sync to the destination immediately. Schedule Backup The task will be executed on schedule between the source and the target. iSCSI Backup The iSCSI volume will be backup to the destination as a single ﬁle. iSCSI Import The iSCSI ﬁle can be imported from the iSCSI backup back to the destination as an iSCSI volume.

Import: click on “Import” and a screen will appear as below. 1. If there is an external device installed on system such as USB disk, then it will be listed in the Source pane.
