Parameter |
Description |
|---|---|
|
Allow CI pruning of backup jobs which aged from all copies |
Definition: Specifies that the data aging must prune the content index from the Search Engine even if the backup data is spread across tape and magnetic libraries. Default Value: 0 Range: 0 (disabled) or 1 (enabled) |
|
Consider inactive copy for Auxiliary Copy check by Data Aging |
Definition: Specifies that the source copy data will not be pruned if it is not copied on the inactive copy. Default Value: 1 Range: 0 (disabled) or 1 (enabled) Usage: If a secondary copy is created for a storage policy, all source copy data required by that destination copy – either synchronous (all data) or selective must be retained until a successful auxiliary copy operation has been completed. This action may not be desired if (a) you are creating secondary copies now with the intention of them holding data at a later point-in-time. Or (b) you forgot to delete a secondary copy and the data movement is no longer required. In either case, you can set the copy status to inactive and set this parameter to 0 (disabled), enabling subsequent Data Aging operation to prune all data being retained solely for pending auxiliary copy operations to now inactive copies. |
|
Days to consider for pending logical pruning for Deduplication pruning threshold event |
Definition: This parameter allows you to generate an event message when the number of deleted records are older than the 7 days and meets the threshold value specified in the Max number of records pending logical pruning for Deduplication pruning threshold event parameter. Default Value: 7 days Range: 1 – 100 days Usage: For example, you have set the number of days to four on Friday (01-20-2013) and the threshold value in the Max number of records pending logical pruning for Deduplication pruning threshold event parameter is set to 10,000. If the number of deleted records older than past Monday (01-16-2013) is greater than the threshold value that is 10,000, then an event message is generated. Once the value is set the check is performed every day to verify both the criteria. |
|

If you do not want to prune the previous backup cycle until a synchronization operation has successfully run in the current cycle, then ensure that you select the Reconcile Backup check box on the Subclient Properties dialog box and enable the Retain jobs in previous cycle until Source Files and backup index are synchronized in latest cycle parameter. The Data Retention Forecast and Compliance report displays all the jobs which are not pruned as they do not qualify for the synchronization check. Note This configuration parameter is not applicable for subclients that have days only retention configured. For such subclients the backup jobs will be pruned depending on their respective data aging selection. Default Value: 1 Range: 0 (No) or 1 (Yes) When the value is set to '1', and the Reconcile Backup check box is selected on the Subclient Properties dialog box, then the previous backup cycle is not pruned until the synchronization operation runs successfully in the current cycle. When the value is set to '0' or the Reconcile Backup check box is cleared on the Subclient Properties dialog box, then the previous backup cycle is pruned depending on the storage policy copy data aging selection. Usage: By default, the value is set to 1 and the newly created subclients will have the option enabled by default. For subclients created prior to Service Pack 7, you can enable the Reconcile Backup check box in the Subclient Properties dialog box. |
