The daily backup of my boot drive runs at 5:00 am. When I got to my Mac this morning, SuperDuper! was open, with the progress bar appearing to indicate the copy was nearly complete.

The log shows these lines at the end:

| 05:33:45 AM | Info | /dev
| 05:33:45 AM | Info | /net
| 05:33:45 AM | Info | /home
| 05:33:45 AM | Info | /Sandbox
| 08:35:06 AM | Info | Disk disk8 mount changed!
| 08:35:16 AM | Info | Disk disk8 mount changed!
| 08:35:16 AM | Info | Disk disk8 vanished!

"disk8" does not appear earlier in log.

What does this mean?

While I was researching this problem here in the forum, SuperDuper! apparently completed, with no Growl notification. Fortunately, I had captured a copy of the SD log in BBEdit while SuperDuper! was stalled.

We're logging disk mount/unmount events during the backup, in case those events can shed light on failures that might occur during a backup operation.

Those mounts are likely Time Machine local (snapshot) or remote (network) volumes.

Is there anything further on this? I just got a similar message and the backup appeared to have stalled. I finally cancelled it. I'll attach a screenshot of the last few lines of the log. I am not using TimeMachine and there's no network drive involved here.

If it's "stalled", it's likely going to get those logs if you have any other volumes being mounted: we're logging them all in case they're relevant.

Are you running CrashPlan?

"Are you running CrashPlan?"

No. (I don't recognize that name.)

OK. Next time this happens, if it happens again, drop me a note to support *before* stopping it, so we can diagnose what's going on.

Was this on High Sierra (10.13.x) or an earlier version?
