User Guide

￿All files available on the 1st day of each quarter within the last 12 months

￿All files available on the 1st day of each year within the last 7 years

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.:

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.
