On the system that is running VERITAS Backup Exec, set up VERITAS Backup Exec
so that it is able to backup user shares.
You can find this option in
Tools—> Options menu on the Network tab.
12
In the Veritas Backup Exec Backup Selections window, browse to your NAS appliance
under Entire Network .
13
Select the share name that you created for your persistent image.
14
Deselect the Persistent Storage Manager State directory when performing persistent
image backups. This directory contains files needed for persistent images. However, to
save space on your backup media, backing up these files is not recommended.
15
Click Backup .
16
Select Run Now to run the backup now or Schedule to schedule your backup job to
run at a later time.
NOTE: Although you are backing up your persistent image from a Network Share, it will not
create network traffic if you are backing up to a local backup device.
Limitations on Backing Up Persistent Images
• You cannot do incremental or differential backups of persistent images.
• You cannot use GFS rotation schemes when backing up persistent images.
• You cannot schedule a backup of a persistent image.
You must do a manual backup of persistent image files because each persistent image
file name is unique in that it includes the date and time (hour-minute-second) that
the persistent image was taken.
• When you restore a persistent image, you must redirect the restore to a location other
than the original persistent image location. A restore to the original location will not
be successful.
Restoring Persistent Images From Tape Backup
NOTE: Do not use Computer Associates ARCserve to restore persistent images.
To restore your persistent images from tape backup, perform the following steps:
1
On the system on your network that is running Veritas Backup Exec, click the Restore
Selections tab to bring up the window that lists your previous backups.
2
Browse to your backup of the persistent image that you want to restore and select it by
clicking the check box next to it.
