SuperDuper! process disappears and leaves no log

[mykmelez]

Today I initiated a backup by plugging my external drive into my computer, whereupon SuperDuper! started up automatically, as it is configured to do. The backup started successfully, but at some point I noticed that SuperDuper! was no longer running. I restarted it and opened its log, but the log only contains entries from my previous backup (last Tuesday, November 3).

Did SuperDuper! crash (without triggering Mac OS X's crash reporting dialog)? Did it succeed but not write a new log?

I checked the syslog and found these entries, which were written around the general time I noticed that SuperDuper! wasn't running anymore, so they could have been written shortly before I noticed it:

FWIW, the last few times I checked the backup's progress, it was in the same place, which is usually an indication that it's copying one of my large 20-40GB VMware Fusion VMs. I did not have Fusion running during the copy, though (so the VM copies would be consistent), although I did have other applications running (Terminal, Adium, Firefox, Thunderbird, and Komodo IDE).
