Also, are you familiar with the powershell toolkit. This is something that you need to work on to get started.

How many controllers are we talking about and about how many volumes?

Could you not just configure the snapshot retention period for each volume using system manager? In CDOT you would just create a SnapShot Policy and assign the volumes to it. In 7 mode just use set the retention to 6 daily and 1 weekly. You would not have to run a script everyday for this. If you have a lot of them you could use powershell to assign a policy to all of the or DFM "Run Command".
