This changes the logic of detecting if a backup is in progress by
writing out the snapshot and PID of the process making the backup. This
improves the situation where a previous backup was killed in a non-clean
way. Clean failures in the sense of a proper exit (also non 0 exit
statuses) or using ctrl-c was already handled by traps.
This just removes the in-progress file if the process is no longer
running after the backup. It then cleans up the in-progress file and
lets the rest of the system clean up the failed backup.
Fixes #99

I think we can improve the error message. Was there a reason to drop $GHE_HOSTNAME from it?
How about:
Error: detected a backup of $GHE_HOSTNAME already in progress.

Comment seems outdated based on the additional feedback, so going with the last mentioned suggestion.

I've left some comments on the error copy, but the functional changes make sense to me. |
