Hi mitya!
Use mminfo to find the ssid and cloneid of the savesets you want to recycle/delete. Replace xxx below with the name of the disk device, and replace mm/dd/yy with a date. Since we use < i.e 'smaller than', all savesets that are older than this date will match. You can ofcourse add more querys such as client name and so on. Try out the mminfo querys before you 'go live", so that you don't mess things up.
After this, you need to set the status of these savesets, or just delete them if thats what you want. You need to use nsrmm in a loop to do this.
Windows:
1) mminfo -av -xc/ -r ssid,cloneid -q "volume=xxx,savetime<mm/dd/yy" |find /V "ssid/clone-id" > temp.txt
2) for /f %i in (temp.txt) do nsrmm -o recyclable -S %i
Unix (use in a script):
1) mminfo -av -xc/ -r ssid,cloneid -q "volume=xxx,savetime<mm/dd/yy" | sed 1d > $LISTFILE
2) while read SSID
do
nsrmm -o recyclable -S $SSID
done < $LISTFILE
Cheers!
