> How does this compare to rsnapshot, which also uses rsync and hard links?
>From my cursory glance at rsnapshot, it looks very similar to rsback.
They are both run via cron jobs.
Flashback runs as a daemon.
I don't want to back up my laptop at 2:00am. I want to back it up when
the previous backup is at least 24 hours old. If the machine is powered
off or is off the network, I want to catch it as soon as it comes back
online. This is more like what BackupPC does.
I do this by sitting in a loop and checking the times since the last
backup. It attempts to run rsync. If it fails, another attempt will be
made next time through the loop.
