How NetBackup Selects Media in a Robot
When NetBackup automatically selects a volume in a robot, it proceeds as
follows:
SUSPENDED
NetBackup can automatically set volumes to the
SUSPENDED
state as explained in “Allow Media Overwrite” on page 482 or
“Automatic Media Suspend Or Device Down” on page 449.
You can also use the
bpmedia
command to manually suspend or
unsuspend volumes.
When an active NetBackup volume is suspended:
• Backups are still available for restores (if they are expired you
must import them first).
• The volume is unavailable for future backups until the retention
period ends for all backups that are on it. At that time, the sus-
pended volume is deleted from the NetBackup media catalog
and deassigned from NetBackup.
FROZEN
NetBackup can automatically set a volume to the FROZEN state
(see “Allow Media Overwrite” on page 482). You can also use the
bpmedia
command to manually freeze or unfreeze volumes.
When an active NetBackup volume is FROZEN:
• Backups are still available for restores (if they are expired you
must import them first).
• The volume is unavailable for future backups.
• The volume never expires, even when the retention period ends
for all backups that are on the media. This means that the media
ID is never deleted from the NetBackup media catalog and,
therefore, remains assigned to NetBackup.
IMPORTED
NetBackup automatically sets volumes to the IMPORTED state if
they are imported to this server.
When an active NetBackup volume is IMPORTED:
• Backups are still available for restores (if they are expired you
must import them first).
• The volume is unavailable for future backups until the retention
period ends for all backups that are on it. At that time, the
imported volume is deleted from the NetBackup media catalog
and deassigned from NetBackup.
