I have been using rsnapshot for backing up a few servers quite successfully and have been relatively pleased with it save for one major issue: monitoring.
For those of you who use rsnapshot, how do you monitor it? I would like some way to verify that rsnapshot is running, that it is pulling down files and that in general, it is working the way it should be. And if it's not, I should be emailed right away so I can fix the failure.
Obviously, this is no replacement for regular tests of restoring files, which is how I've caught problems in the past. I just would like something a little more automated to add to my testing regimen so some of those errors can be caught and corrected more quickly.
What do you use to monitor rsnapshot? Or, what is your backup monitoring strategy in general?
