Snapshot managed backups still running

The backup was scheduled for Th12am, and is still running - can't do a new backup.
I installed the managed back up on 4 sites yesterday to test.
Norwellwomensclub.org - everything went fine
safeandsoundschools.org - everything went fine - fairly large site and backupbuddy wouldn't work - so very pleased here.
Westhillcounsel.com - getting <empty response> Tried a couple of things in forums, didn't help.
Budibar.com - still running
