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.
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. |
• |
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. |
6 |
To determine the overall size of a disk, click the applicable disk, and select Disk Size from the context menu. |
• |
Device: The number and type of the disk. |
• |
Size: The size of the selected disk. |
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.

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. |
• |
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. |
