Changing the Attributes for a Volume
144 NetBackup Media Manager System Administrator’s Guide for Windows
▼
To allow an unlimited number of mounts
❖
Select Unlimited (Unlimited is the default).
▼
To set a specific limit for the number of mounts
1.
Click Number.
2. Enter a number or click an arrow to specify the number.
When the limit is passed the volume can still be read, but it will not be mounted for a
write.
Specifying zero (the default) is the same as selecting Unlimited.
Expiration Date
Expiration Date does not apply to cleaning tapes.
You can change the expiration date for the selected volumes. This date refers to the age of
the volume and is the time at which the volume is considered too old to be reliable. When
the expiration date has passed, a volume can still be read but will not be mounted for a
write.
When you add a new volume, there is no default expiration date.
The expiration date is not the same as the retention period for the backup data on the
volume. The expiration date that you can set in this dialog refers only to the physical
expiration of the volume and is independent of the backup data written on the volume.
The backup data expiration date is managed separately by the application that is using the
volume. In the case of NetBackup, the expiration date for the data is set as the retention
level during schedule configuration.
