If you aren't worried about the actual boot environment and /dev items, I back up using rsync -avXA --exclude-from=/etc/skipdirs.rsync / /newmountpoint "/newmountpoint" is typically where I mount backup media such as "/media/3TB-External-Drive" The file "/etc/skipdirs.rsync" contains: /proc/* /sys/* /dev/* /media/* /var/log/journal/* **/.cache/google-chrome/*** **/.ccache/*** /BACKUPS/* /run/media/* The first three are sorta mandatory as they're transient and won't translate to a new system. The fourth keeps me from looping through mounted media (such as the backup media) and the rest just keep from backing up logs and crap that the new machine doesn't care about or need. This has worked for me for backup purposes and restoring machines from fresh OS installs. If you need LIVE backup or full bare-metal restoration media, there are things like Clonezilla, mondorestore, Acronis (commercial) and lots of others.
