Before backing up any portion of a NetVault Bare Metal Recovery Client’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.
To verify the geometry and size, perform the following steps.
1 |
With the NetVault Bare Metal Recovery Client booted using Plug-in Offline Client, as outlined in Booting a NetVault Bare Metal Recovery Client with Plug-in Offline Client, access the NetVault Backup Server, and start the NetVault Backup WebUI. |
2 |
3 |
4 |
On the NetVault Backup Selections page, double-click the NetVault Backup Server — the system containing the Plug-in Server — to open it. |
6 |
To determine the Disk Geometry, select the applicable disk, and then select Disk Geometry from the Actions list. |
• |
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. |
8 |
To determine the overall size of a disk, select the applicable disk, and select Disk Size from the Actions list. |
• |
Device: The number and type of the disk. |
• |
Size: The size of the selected disk. |
Before performing a NetVault Bare Metal Recovery backup, consider the following important points:
• |
When Disk Raw Mode is selected, not only is the disk in use backed up, but the entire disk is as well. For example, if 6GB are in use on a 30GB partition, 30GB of media is used to back up the disk. Only use the Disk Raw Mode option when a complete hard drive is selected for a Plug-in Server backup, that is, not an individual partition. |
• |
Dynamic disks must be backed up by using Disk Raw Mode to maintain partition information. |
• |
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 Backup Administrator’s Guide.

3 |
In Job Name, specify a name for the job. |
4 |
5 |
Locate the machine acting as the NetVault Backup Server, that is, the machine with the Plug-in Server installed, and double-click it to open it. |
6 |
In the list that is displayed, locate the Plug-in Server, labeled “VaultDR APM,” and double-click it to open it and display the hard disks on the client system. |
• |
Primary Partition: Each hard disk can contain up to four different “true partitions.” They are called the primary partitions, and can be individually selected for backup. |
• |
Extended Partition: This partition is the space on the hard disk not allocated to the primary partitions. This type of partition cannot be selected for a backup. To add it, the entire drive must be selected. |
• |
Logical Partition: Logical partitions allow multiple system images to run in one machine. This option can be multiple instances of the same OS or different systems. Logical partitions can be individually selected for a backup. |
8 |
The next step involves creating the Backup Options Set.
1 |
• |
Disk Raw Mode: Select this option if you want all partition information for a selected hard drive ignored and a “bit-by-bit” backup of the entire disk image 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. |
• |
Compression: To compress data on the NetVault Bare Metal Recovery Client 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 NetVault Bare Metal Recovery 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. |
• |
Back up used blocks only for NTFS partitions: If you are using the Windows PE-based Plug-in Offline Client and the backup includes Windows®-based partitions, select this option if you only want to back up the used blocks. If you clear this option, a discrepancy (4 K) between the backup data and the size of the NTFS volume might be reported in the binary log; this option is working as intended, and does not affect a restore. If you are using the Linux-based Plug-in Offline Client, this option is visible but not functional. |
