How to Delete savesets from a specific volume

Probably you'll have to use something like:

mminfo -q "volume=VOLNAME,savetime>MM/DD/YY" -r ssid

Then for each ssid use nsrmm -d to remove them. Just create a small script that does this, it's not that hard.

And just if you're not aware of this: nsrmm -d will delete the saveset info from the media db. Data on a file device will be removed as well, but if it's a tape, data will remain there until you relabel it, ok?

I would just change -r to read -r ssid,cloneid as in case of cloning with longer retention you may wish to leave other volume(s) with copy not affected by delete operation.

Your nsrmm command would also change if your are looking at deleting only a particular clone of a saveset. You would need to specifically mention the cloneid along with the ssid.
