What to choose for backup and recovery of Linux on bare metal?

Clonezilla - has-style interface next->next->done, but it all comes down to 1st menu item to kneading people have not had the opportunity to make a mistake.

* rdiff-backup
* rsync
* dd

Personally, I prefer the second option, but it is one - off- there are no increments and diffu. A little difficult it may seem, the recovery - needed hands to mark the screw and to write the loader. However everything can be automated. :)

Personally I use TimeShift on Debian, good enough for Ubuntu. TimeShift is a GUI for rsync add - on and not only.

Normal rsync reliably does everything
