Prerequisites for an offline backup
•
Completing the backup

Prerequisites for an offline backup

Before initiating a backup with the Plug-in Server, review the following topics for details on prerequisites that must be met.

 
* 
CAUTION: Even if there is no difference between the system devices in a backup and a restore, the order of the disks might be different. If the restored data is started without performing a rename, any data that exists on the disks is lost. To compare the information of the physical disk at backup and restore, note the Disk Geometry and Device Size at backup.

Verifying Disk Geometry and Device Size

Before backing up any portion of a NetVault Backup 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 Backup Selections page, and double-click the NetVault Backup 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.
•

•
Start Cyl: Displays the origination point (cylinder) for the various partitions.
•
