DS-User F1 Help for GUI (Context-Sensitive) : Retention Rule Wizard - Time Retention Options
 
Retention Rule Wizard - Time Retention Options
Use this dialog box to define the time retention options.
When a retention rule is enforced on a backup set, the process will delete all of that backup set’s data, except for file generations that fall into one of these selected time-retention options.
The retention options in a retention rule can overlap, with the result being that the option that leaves the most generations for the longest time is applied.
 
Time-based retention options
Generations of a file that fit these categories will be kept. Everything else will be deleted.
• For Online backup sets, this deletes data from online storage (on DS-System).
• For Local-Only backup sets, this deletes data from local storage (because Local-Only backup sets are exactly like Online backup sets except that they backup to the DS-Client’s local storage).
Keep most recent generations [...]
The specified number of generations of a file will be kept. Any generations over this number will be deleted (unless they qualify for another retention option).
For a Microsoft SQL Server database backup based on the Transaction Log Only database backup policy, you must specify a value of 0 in this box.
For all other backup set types, specify a value of 1 or higher in this box.
Keep all generations for the last [...]
All generations that fall within this time period will be kept. Any generations outside this time period will be deleted (unless they qualify for another retention option).
For a Microsoft SQL Server database backup based on the Transaction Log Only database backup policy, select this check box and specify a time period.
