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.

Inherit job retention from source copy

Select this option to inherit the job retention for manually pinned jobs in the source copy.

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.

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.

Ignore Job Dependency Check

Applicable only for snap copies.

You can select this option when the snap copies are configured with days only retention with 0 cycles. When you select this option, jobs are retained based on days retention. The latest incremental jobs (that have not met days retention) will not retain previous jobs in that cycle that are past days retention.

Spool Copy (No Retention)

Sets the retention rule on a storage policy copy to 0 days and 0 cycles. For NAS, Windows (CIFS), and UNIX (NFS) agents under NetApp and Huawei NAS clients, data backed up using IntelliSnap backup, the retention rule is set to one job instead of zero jobs (no retention).

Retain Snaps by Number of Jobs

Specifies the number of IntelliSnap 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

The amount of time that you want to retain the data that is backed up via this storage policy copy, and the number of full backup cycles that you want to retain the data that is backed up via this storage policy copy.

Note:

If this storage policy copy is added as a dependent copy of a storage policy with global deduplication, then you can view the storage policy copy retention rules from the Dependent copies tab of the storage policy with the global deduplication.

Select from the following options:

• Infinite

  Specifies that data will be retained for an infinite amount of time.

• 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).

  Default is 15 days and 2 cycles.

For more information, see Data Aging - Data Retention Rules.

Extended Retention Rules for Full Backups

• ForInfinite or n Days

• Keep

  Select the type of full backup to which the retention applies.

  • All Fulls

    All full backups.

  • Hourly Full

    The first or last full backup of every hour (each hour starts on 12:00am). This option is only applicable for Snap Copies.

  • Daily Full

    The first or last full backup of every day (each day starts on 12:00am). This option is only applicable for Snap Copies.

  • Weekly Full

    The first or last full backup of every week (each week starts on Friday).

  • Monthly Full

    The first or last full backup of every month (each month starts on the first of the month).

  • Quarterly Full

    The first or last full backup of every quarter (each quarter starts on January 1, April 1, July 1, and October 1).

  • Half Yearly Full

    The first or last full backup of every half year (each half year starts January 1, and July 1).

  • Yearly Full

    The first or last full backup of each year (each year starts on January 1).

    Note

    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.

• 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.

• For The Daily Full Rule and Hourly Full rule the Day starts at:

  Allows you to select the time for which the hourly/daily extended retention rule will start. The default start time is 12:00 am. This option is applicable for Snap Copies.

• For Weekly Full Rule the Week starts on:

  Allows you to select the day of the week for which the weekly extended retention rule will start.

• For Monthly Full Rule the Month starts on:

  Allows you to select a particular day of the month for which the monthly extended retention rule will start. The default start time is the first of the month.

• For all rules keep the:

  • First full backup of time period

    If selected, the first full backup of each extended retention rule will be retained.

  • Last full backup of time period

    If selected, the last full backup of each extended retention rule will be retained, providing there are no remaining full backup schedules for the same subclient during that time period.
