Backing Up Dell ActiveArchive™ Persistent Images
Backing up persistent images eliminates the possibility of files changing during backup. Persistent images always contain the
data that existed when the persistent image was taken.
NOTICE: Backing up persistent images is a complex procedure and should be performed only by advanced backup
administrators. If you are not an advanced backup administrator, it is recommended that you use the available open
file agents in VERITAS Backup Exec to back up your open files rather than backing up persistent images.
NOTICE: Do not use Computer Associates ARCserve to back up persistent images.
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 perform a manual backup of persistent image files because each persistent image filename 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 is not successful.
To back up a persistent image, perform the following steps:
1. Use the NAS Manager to create a persistent image.
