Hi, I'm looking for a list which paths/files are safe to exclude for a full system/home backup.

Considering that I have a list of installed packages.

  • /home/*/.thumbnails
  • /home/*/.cache
  • /home/*/.mozilla/firefox/*.default/Cache
  • /home/*/.mozilla/firefox/*.default/OfflineCache
  • /home/*/.local/share/Trash
  • /home/*/.gvfs/

  • /tmp/

  • /var/tmp/
  • not real folders but can cause severe problems when 'restoring'
    • /dev
    • /proc
    • /sys

What about...

  • /var/ in general?
  • /var/backups/ - can get quite large
  • /var/log/ - does not require much space and can help for later comparison
  • /lost+found/
