Control how many past Snapshots we keep and the rotation policies
Snapshooter offers a range of retention policies (achieving), so you can set how many daily, weekly and monthly snapshots you want to retain. This gives you the ability to keep backups for a lengthy amount of time without having to pay to keep individual backups. For example, you might want to keep the last 12 monthly backups to give you a range of a year without paying for 365 daily snapshots. You are entirely free to keep as many snapshots as you want of each type.
