If there's any log of a terminal event anywhere, it will be in either
syslog or the kernel log. But if it's a problem which can be logged, it
can also be survived, and having written something useful to syslog,
the kernel is not then going to crash hard. I don't think you'll find
anything logged directly, the best you can hope for is some kind of
warning about disc or RAM errors or similar, during the backup before
the crash. That's not very likely, as such errors would probably corrupt
the backup and almost certainly the backup will terminate early,
without the machine crashing.
None of that software (in Stable at least) is new and potentially
flaky, and it must be heavily tested by many people every day. I'd
still go with hardware, perhaps being unusually stressed by the backup.
Is it possible to change the backup destination type i.e. if it's going
to a local disc at the moment, send it to a USB drive or network share,
or vice versa? Can you monitor and log the CPU temperature and fan speed
during the backup?
