If you use snap sched you can do exactly that, except your snapshots will be named daily0 daily1 and daily2, rather than the ss-YYYYMMDDHHmm you currently use.  If you can live with that your ok. 

If the naming convention is important for some reason then you will need to develop a host based script to handle it.  Unfortunately, I don’t have one available but someone else might.

Subject: Automatically delete snapshots based on number and not space availability

Greetings,

I take a daily snapshots (named ss-YYYYMMDDHHmm) of several volumes on my filers.  I would like to automatically delete the oldest snapshot (assuming it's not busy) when a certain number of snapshots are present in the volume (ie, only keep the latest 3 snapshots).  Is this possible?  If not, does anyone have any scripts where it can be done from a host?

TIA,

Daniel
