Scheduling delta chain optimization
You can schedule when the DS-System runs delta chain optimization tasks. During optimization, the DS-System enforces the master-delta chain length to the files in each directory. For more information, see
“Configuring the delta chain settings”.
To schedule delta chain optimization:
1. On the Setup menu, click Schedule and then do one of the following:
• To add a scheduled delta chain optimization task, click Add.
• To modify a scheduled delta chain optimization task, select a task, and then click Edit.
2. On the Select Schedule Type page, select Delta Chain Optimization, and then click Next.
3. On the Select Schedule Time page, do the following:
a) Under Detail Type, select the frequency of the schedule.
b) Under Daily Frequency, beside Start at, specify the time at which the schedule must start.
• To specify a time and day when the scheduled activity must end, select the End at... after... day(s) from start day check box, and enter the time and the number of days.
c) Click Next.
4. On the Delta chain optimization option page, do the following:
a) To specify which items you want to be optimized, in the Optimization selection box, select one of the following:
• All backup sets – All the backups on the DS-System are optimized.
• Modified directories – Only directories flagged by the DS-System as modified since the last optimization task was run are optimized.
• Modified backup sets – Only modified backups and their directories are optimized.
b) To specify the number of optimization processes that can run concurrently, in the Concurrent optimization processes box, enter the number of processes.
c) Click Finish.
5. Click Close.
