To do so, you need to setup your advanced retention policy as follows:
Type = Daily; Number of copy to keep = 7
Type = Weekly; Frequency = Saturday; Number of copy to keep = 4
Type = Monthly; Frequency = Day 1; Number of copy to keep = 3
Type = Quarterly; Frequency = Day 1 of Jan, Apr, Jul, Oct; Number of copy to keep = 4
Type = Yearly; Frequency = Date 01-01; Number of copy to keep = 7
Assuming today is 17-Jan-2006, if [Remove retention files for overlap policy] is NOT enabled, a total of 22
snapshots (provided you have run backups daily for more than 7 years) will be kept on the server accordingly, i.e.:
Daily Weekly Monthly Quarterly Yearly
16-Jan-2006 14-Jan-2006 01-Jan-2006 01-Jan-2006 01-Jan-2006
15-Jan-2006 07-Jan-2006 01-Dec-2005 01-Oct-2005 01-Jan-2005
14-Jan-2006 31-Dec-2005 01-Nov-2005 01-Jul-2005 01-Jan-2004
13-Jan-2006 24-Dec-2005 01-Apr-2005 01-Jan-2003
12-Jan-2006 01-Jan-2002
11-Jan-2006 01-Jan-2001
10-Jan-2006 01-Jan-2000
If [Remove retention files for overlap policy] is enabled, only the following snapshots are kept:
Daily Weekly Monthly Quarterly Yearly
16-Jan-2006 14-Jan-2006 01-Jan-2006 01-Jan-2006 01-Jan-2006
15-Jan-2006 07-Jan-2006 01-Dec-2005 01-Oct-2005 01-Jan-2005
14-Jan-2006 31-Dec-2005 01-Nov-2005 01-Jul-2005 01-Jan-2004
13-Jan-2006 24-Dec-2005 01-Apr-2005 01-Jan-2003
12-Jan-2006 01-Jan-2002
11-Jan-2006 01-Jan-2001
10-Jan-2006 01-Jan-2000
The weekly policy overrides the daily policy so the snapshots of 10-Jan-2006, 11-Jan-2006, 12-Jan-2006, 13-Jan-
2006 and 14-Jan-2006 are removed. The monthly policy overrides the weekly policy so the snapshots of 24-Dec-
2005 and 31-Dec-2005 are removed. The same applies to the monthly, quarterly and yearly policy giving a total
of 11 snapshots.
