If you enable the auto media management feature for a standalone device, Backup exhibits the following behavior when a volume becomes full during a backup:

1.Backup issues a notification that it is waiting for a writable volume.
time, Backup waits for the full, verified volume to be unmounted.

At the same

2. Backup monitors the device and waits for another volume to be inserted into the
device.
3. After a volume is detected, Backup checks that the volume is labeled. If so,
Backup mounts the volume. Backup checks to see whether the volume is a
candidate to write data to. If so, the write operation continues. If not, Backup
continues to wait for a writable volume to continue the backup. 4. If the volume is recyclable and is a member of the required pool, Backup recycles
it the next time a writable volume is needed.
5. If the volume is unlabeled, Backup labels it when the nextwritable volume is
needed for a save.
In general if a non-fullvolume is unmounted from a standalone drive and you enabled auto media management, Backup waits for 60 minutes before it automatically remounts the volume in the drive. This hour is considered a reasonable delay to give you or an operator time to unload the volume after unmounting.

Caution - Backup considers volumes that were labeled by a different application to be a valid relabel candidate if automedia management is enabled. Once Backup relabels the volume, the previously stored data is lost.

Storage Volume Status

Different reports and windows provide information on the status of storage volumes using parameters such as Written, %Used, Location, and Mode. This section defines some of the most common terms contained in reports about volumes. In the Backup administration program, the volume name displayed is the same as the name that appears on the volume label. At the end of the volume name, the following designations might be displayed:
*(A), which indicates an archive storage volume
*(R), which indicates a volume that is considered "read-only"
