Prerequisites for an offline recovery

Before recovering the NetVault Backup Server, the following conditions must be met:

•
Provide either a new disk or an existing disk that has had all existing partitions removed.
 
* 
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. For more information, see Performing a restore in which Disk Numbers are different from the backup.
•
If your VM is based on Windows Server 2012 or 2012 R2, update the VMware configuration file to use the E1000 adapter. For more information, see Using a Windows Server 2012-based virtual machine.
Performing a restore in which Disk Numbers are different from the backup

In some instances, the Disk Number assigned to a drive during backup might be different for the restore. To work around this issue, note the Disk ID and disk order displayed on the Create Selection Set page, use the Plug-in Offline Client to boot the machine that is targeted for the restore, and then note whether the disk order is different. If the order is different, use the Rename option during the restore process to prevent data loss.

To determine whether the disk order is different, perform the following steps.

1
In the Navigation pane of the NetVault Backup WebUI on the NetVault Backup Server, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug-in Server from the Plugin Type list.
3
In the saveset table, double-click the applicable saveset to open it.
4
When the backed-up client machine is displayed, double-click it to open it and list the disks that were backed up.
5
Note the information displayed within the parentheses for each disk.
6
Use the Plug-in Offline Client to boot the NetVault Bare Metal Recovery for NetVault Backup Server Client that is targeted by the restore, access the NetVault Backup Server, and open the NetVault Backup Selections page.
7
Drill down to the disk-level of the client, and note the current disk order.
If the order is different, use the Rename option during the restore.

Booting into NetVault Bare Metal Recovery for NetVault Backup Server

The first step in the recovery process is to use the NetVault Bare Metal Recovery for NetVault Backup Server CD to boot the machine. This process requires the CD previously created during the Offline Backup process.

1
Use the CD created in Booting into NetVault Bare Metal Recovery for NetVault Backup Server to boot the server; if connected through a USB port, the port must use the 3.0 protocol or earlier.
The server boots into X graphical multiuser mode and starts NetVault Backup and the drdaemon process.
2
If you want to enable multipath support, perform the following steps:
a
In the NetVault Bare Metal Recovery Daemon process terminal (command prompt), press <Ctrl+C> to stop the process.
b
To open a new NetVault Bare Metal Recovery Daemon process terminal, double-click the Terminal icon on the desktop.
c
At the command prompt, enter the following commands:
cd /vaultos_file
./drdaemon -o mpath
 
* 
NOTE: You can enter the -o mpath and -p port_number options together.
3
Detect and add the locally-attached tape library or standalone tape device through NetVault Backup.

Importing the indexes to the NetVault Database

The next step is to select the dedicated DR target media for your recovery and import the indexes to the NetVault Database.

1
In the Navigation pane of the NetVault Backup WebUI, open the Manage Devices page.
2
On the Manage Devices page, click the Manage Device icon for the drive or slot that contains the media that was used during backup, for example, BMRMedia, and is now marked “FOREIGN.”
3
On the Tape Drive Management page, click Scan.
NetVault Backup imports backup indexes stored on the FOREIGN media to the NetVault Database.
