Ah, I think I understand what might be going on. This is a VM I had
been running under VMWare Fusion 2.0, and I copied its entire folder
over to a new Linux partition. Somehow it's still running these snapshots and I believe the GUI status message calls them "AutoProtect." I will check ps or top the next time one runs, and see if "vmrun snapshot" is actually the process at work under the covers. If so, I think the cron rescheduling will work; if not, I'm not sure what to do.
