Retention rules

1. Click How long to keep.
2. In Cleanup, choose one of the following:
   • By backup age (default)

     Specify how long to keep backups created by the backup plan. By default, the retention rules are specified for each backup set separately. If you want to use a single rule for all backups, click Switch to single rule for all backup sets.

   • By number of backups

     Specify the maximum number of backups to keep.

   • Keep backups indefinitely

Note  A backup stored in a local or network folder cannot be deleted if it has dependent backups that are not subject to deletion. Such backup chains are deleted only when the lifetime of all their backups expires. This requires extra space for storing backups whose deletion is postponed. Also, the backup age and number of backups may exceed the values you specify.
