Yes, but not frequent enough
Backups are essential for me, but restore is more important.
I have much to learn with linux and make silly mistakes and having to redo all that I had previously done, replace and reconfigure is a real bind and a big waste of time if I can backup, experiment, fail and step back to the working backup.
I also have a text file with a list of commands that are all in order so should I really screw up I can just copy/paste the sequence to get back up and running.
Still, bu/restore is the first option when I goof!
