I see a couple of problems here:

• You copy all games every time any game hosts. Which clobbers the backups of all games other than the one about to be hosted.
• You only maintain a backup of the latest turn. This will cause trouble when the game manages to **** itself up so that it crashes at next hosting, because by the time you notice it crashing, you've clobbered the backup from before it broke.
  (Yes, this can happen. Guess what made me think it was a good thing I was already backing up all truns?)

If you look approximately halfway up the thread, I've posted a backup script that has neither of those particular issues.

You are correct, the script is simple but easily altered to backup only one game.. in this case /home/dom/dominions3/backup/Rivers/
I hope that the game won't crash and use this one.

Your script was too much for me and I didn't understand it. Thanks for your input. I will look it again when I find the time.

Most of my backup script is about finding the current turn number and handling edge cases like being somehow called to backup a non-existent game (not detecting conditions like that will at best result in the script crashing and at worst data loss as it goes blindly ahead to do something stupid).


Doing

--preexec /home/dom/backup.sh "$GAME"

and

#!/bin/bash
rsync -a "/home/dom/dominions3/savedgames/$1" /home/dom/dominions3/backup

would have your backup command be parametrised by game name, so it'll backup each game to separate directory. Though I guess that might have been what you meant?

Looks like edit period ran out... It should have been

--preexec "/home/dom/backup.sh \"$GAME\""

It works perfectly!
