Events, and Alerts if configured, are generated. This value should be set to the maximum number of tapes you anticipate consuming in a 48 hour (weekend) period. This should then give you ample warning to replenish the media in the pools to avoid data protection failures from insufficient media. |
|
Convert next backup to differential when incremental/differential jobs are deleted |
Definition: Specifies that if a job is pruned manually, then the next backup job for the subclient will automatically be a differential backup. Default Value: 0 Range: 0 (disabled) or 1 (enabled) Usage: If backup jobs are pruned manually, then to ensure data integrity, full backups are run. If an incremental or a differential backup from the most recent cycle is deleted and this parameter is set to 1, then the next backup for the subclient is a differential backup. However, if the most recent full backup is pruned manually, then irrespective of the value set for the parameter, the next job for the associated subclient is a full backup. |
