Tonight I installed Back In Time. I must say, this backup program is very, very nice. It's kind of like Deja Dup but with more control without being crazy overbearing with obnoxious features. Very satisfied with it so far. I ended up setting up a profile to rsync my data over SSH to my server from my laptop. So far, it's worked great. I went into the scheduling feature, which I thought for SURE would be why you'd need the root version. I set backups to run every 5 minutes. Then, I rebooted, and came up to a fresh instance on my laptop. I did not launch Back In Time. Instead, I just opened YouTube and killed 5 minutes while I was waiting for the Back In Time instance to supposedly run another snapshot. Meanwhile, I was in a terminal window SSH'd into my server. To my surprise, I saw another entry come up after 5 minutes as Back In Time had ran another backup. I did not have Back In Time open and there are no crontab entries for it.
So I got to wondering, what's the point of the root version? What does it do that I'm seemingly unaware of?
