When Data Does Not Meet the Criteria for Any Pool

When you use customized pool configurations to sort your data, you might inadvertently omit a client or save set. During a scheduled backup, if data does not meet the criteria for any customized pool configuration, Backup automatically sends the data to the Default pool. Backup uses the Default pool to ensure that all data for clients in a backup group is backed up to a volume.

When Backup sends data to the Default pool, Backup looks for a labeled volume from the Default pool mounted on a storage device. If no Default pool volume is mounted on a storage device, Backup requests the appropriate volume and waits until an operator mounts the volume. If Backup asks for a Default pool volume in the middle of a scheduled backup but an operator is not present to mount a Default pool volume, the backup pauses until an operator mounts a Default pool volume. If you have an operator available to monitor the backups, it is a good idea to keep a volume labeled for the Default pool close at hand in case this situation unexpectedly arises.

If you plan to use Backup for unattended backups, run a test of the backup after making any configuration changes to ensure that all data is written to the appropriate volumes and to avoid an unexpected Backup request for a Default pool volume. For the procedure to test your scheduled backup, see "Immediate Start of a Scheduled Group Backup".
