Use separate state directory for timer script
Browse files Browse the repository at this point in the history
After a backup is completed, update a state directory outside the backup
directory with the current symlinks and timestamp files.  Update the
timer script to use this state directory instead of the backup directory
to avoid spinning up the backup drives if no backup is needed.

Move the client_lockdir out of the backup directory as well.

I've not used Burp,so I could be completely off, but is the state dir supposed to be durable? If so, you might want to move it out of /var/run as some distros mount that in a ramdrive now.

@jkugler, it's safe for the data to be removed and regenerated upon reboot, but /var/cache would probably be more consistent with FHS guidelines. Thanks!
