Just checking that you know even for a full system backup it doesn't
make sense to backup /proc, /sys and other virtual file systems?
Virtual file systems present data about and control of hardware, kernel
and processes. They are dynamically created on every boot, not data
stored on disk which can get lost.
Display mounted virtual file systems:
grep -v '^/dev/' /proc/mounts
Suggest excluding like this:
--exclude '/proc/**' --exclude '/sys/**' ...
This way just the empty directory gets backed up, so on a bare metal
restore the directory is recreated ready to be used as the mount point.
