Warning registered re smartctl. Thanks for the references to the
config, which immediately draw attention to the fact that I have no
idea what the error is.
Looking through those logs for anything at the time of the modification
timestamp on the backuppc xferlog, I can see this one line which
appears about 25 mins after the backup fails:
Oct 17 16:13:48 localhost smartd[1302]: Device: /dev/sdb [SAT], 1
Currently unreadable (pending) sectors
The target USB drive is /dev/sdb1.
But as I said, I scanned the drive and it didn't log any errors. Is
that useful info?
Thanks
Adam
