NetVault Bare Metal Recovery 13.1.2 - User Guide for NetVault Server

Verifying Disk Geometry and Device Size

Before backing up any portion of a NetVault Server’s hard drive, note the Disk Size and the Disk Geometry of the selected drive. If these items are not accounted for, a restore might fail.

Example of how to note the Drive Disk Size and Disk Geometry

A Client drive is divided into three partitions. The primary partition is 10 gigabytes (GB), the first logical partition is 7 GB and the second is 3 GB. A backup of the first logical partition is performed with the Plug-in Server. On restore of the system after a hard drive failure, if the first logical partition was restored, it must be restored to the proper partition — the first logical partition — or the restore fails.

1
Open the NetVault Selections page, and double-click the NetVault Server — the system containing the Plug-in Server — to open it.
2
Open the Plug-in Server by double-clicking it.
3
Double-click the self node displayed under the plug-in to reveal the disks contained within.
4
To determine the Disk Geometry, click the applicable disk, and select Disk Geometry from the context menu.
The Display Device Geometry dialog box displays details about the partition structure of the selected disk.
•
Partitions: Each individual partition is listed here by number and the partition type.
•
Active: Displays the current state of the partition, “Yes” or “No.”
•
Start Cyl: Displays the origination point (cylinder) for the various partitions.
•
End Cyl: Displays the partition’s endpoint (cylinder).
•
Size: Displays the size of each partition.
•
Type: Displays the type of partition.
5
With this information noted, click OK.
6
To determine the overall size of a disk, click the applicable disk, and select Disk Size from the context menu.
The Device Size dialog box displays details about the size of the selected disk.
•
Device: The number and type of the disk.
•
Size: The size of the selected disk.
7
With this information noted, click OK.

Completing the backup

You are now ready to perform a backup of the NetVault Server. The procedure for performing backups includes the steps outlined in the following topics:

•
Selecting data for the backup
•
Setting backup options
•
Finalizing and submitting the backup job

Selecting data for the backup

You must use sets — Backup Selection Set, Backup Options Set, Schedule Set, Target Set, and Advanced Options Set — to create a backup job. For more information, see the Quest NetVault Administrator’s Guide.

 
* 
TIP: To use an existing set, click Create Backup Job, and select the set from the Selections list.
1
In the Navigation pane, click Create Backup Job.
You can also start the wizard from the Guided Configuration link. In the Navigation pane, click Guided Configuration. On the NetVault Configuration Wizard page, click Create backup jobs.
2
In Job Name, specify a name for the job.
Assign a descriptive name that lets you easily identify the job when monitoring its progress or restoring data. The job name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Linux, the name can have a maximum of 200 characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
3
Next to the Selections list, click .
4
Double-click the Plug-in Server, labeled “VaultDR APM,” to open it.
5
When the self node is displayed, double-click it to display all disk device information for this NetVault Server.
You can open disks by double-clicking them. Individual partitions are displayed and made available for selection to back up.
6
Select a single disk, all disks, all partitions, or a single partition of each disk to back up.
7
Click Save, enter a name in the Create New Set dialog box, and click Save.
The name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Linux, the name can have a maximum of 200 characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.

Setting backup options

The next step involves creating the Backup Options Set.

1
Next to the Plugin Options list, click .
2
Select Disk Raw Mode, Compression, or both.
•
Disk Raw Mode: Select this option if you want all partition information for a selected hard drive to be ignored and a “bit-by-bit” backup of the entire disk image to be performed. This bit-by-bit form of data transfer occurs during the restore of this backup as well, thus eliminating the need to format the target drive or remove the partition.
Cases in which Raw Mode is desired include:
•
The selected hard drive does not have a partition table.
•
NetVault Bare Metal Recovery cannot recognize the partition table.
•
You are backing up data outside the Master Boot Record (MBR) and partitions, for example, dynamic disks.
•
Compression: To compress data on the NetVault Server before transfer during backup, select this option. This option reduces overall network traffic during data transfer and also requires less media space to accommodate the backup. This option is useful for partitions that contain a large amount of unused space. Selecting this option usually provides better compression than using a network-based or tape-library-based compression feature.
3
Click Save to save the set.
4
In the Create New Set dialog box, specify a name for the set, and click Save.
The name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Windows, there is no length restriction; however, a maximum of 40 characters is recommended.
