Copy Properties - Retention
Use this dialog box to select the retention rules by which you want to retain the data that was backed up using this storage policy.
Enable Data Aging
Allows the data from this copy to be pruned during a data aging operation as long as the retention rules of this copy have been met. If this option is not selected, the data from this copy will not be pruned and will be retained for an infinite amount of time.
If you disable data aging for this storage policy copy, the current retention rules selected will be saved; they can only be changed when data aging is re-enabled.
Enable Managed Disk Space for Disk Library
Allows the free disk space on the disk media of this copy to be considered before the data on the copy is aged. If there is adequate space on the media, the data will not be aged even if the defined retention rules of this copy have been met. If this option is not selected, data on the copy will be aged regardless of the available disk space. When this option is enabled, the retention criteria on disk mount paths is based on the parameters established in the Thresholds for Managed Disk Space section in the Mount Paths tab of the disk Library Properties dialog box.
For more information on Managed Disk Space for disk data, see Thresholds for Managed Disk Space.
- Managed disk space for disk library prunes the data once the threshold capacity is reached. If the data needs to be preserved for longer period of time, then use Extended Retention Rules settings on the Storage Policy Copy. See Extended Retention Rules for more information.
- This option is not supported for storage policy copy with deduplication.
Do not retain intermediate incrementals and differentials before a new differential
Specifies that intermediate incremental and differential copies preceding a new differential will not be retained. This is useful to minimize wasted disk space.
Spool Copy (No Retention)
Sets the retention rule on a storage policy copy to 0 days and 0 cycles. For NAS data backed up using SnapProtect backup, the retention rule is set to 0 days and 1 cycle.
Retain Snaps by Number of Jobs
Specifies the number of SnapProtect backup jobs to be retained. When the total number of jobs goes above the specified retention number, the remaining jobs are pruned. Default is 24 jobs.
This option is available only on Snap Copy.Basic Retention Rules for All Backups

- Retain for n days n cycles
Specifies the length of the retention period and number of retention cycles (not applicable for agents that do not have cycles).

Each selection must be in ascending order by the number of days and the selected rule type. The Basic Retention Rule must be set before Extended Retention Rules can be selected. Setting start times for the monthly and yearly extended rules do not have any impact on quarterly and half yearly rules.
- All Fulls
- Grace Days
Specify the number of additional days to consider with Extended Retention. If the last full backup job fails with in the defined extended retention criteria, then the next full backup job that ran in the specified grace days will be selected for retention.
Select the jobs from previous tier
Specifies that a full backup job that is designated to be retained can fall within the previous tier's timetable. For example, if two rules are defined as weekly and monthly, this option will allow the job retained for the monthly tier to be selected from the timetable of the weekly tier. Note this option is only enabled when there are two rules defined for extended retention.
