Do you know how Bacula compares to Bareos? Bacula is on my to-do list to look at (also because I need tape backups), but the Bareos fork seems to have a more modern interface - but I've not stress tested either solution. The fact that Bacula has a Debian package and Bareos does not pretty much settles it already, but just curious if someone has actually tried both.
I've tried all of these, and none are as reliable or powerful as Bacula.
It's way more complex at first, but you will have peace of mind. And backup/restore speed is way faster.
You can even easily setup automatic restore jobs to prove your backups work!
