I've been running the same Archlinux installation since October 2011. I couldn't keep it for such a long time without the script from this Full system backup with rsync topic which saved my system three times during three critical moments.
It always worked fine, but I always copied my /home directory with exclusions (e.g. /home/*/.cache/mozilla/*) like it is described in the last bullet of the "Note" field when creating backup.
I'm wondering how good the script is if the /home directory is omitted during backup. So I would like to ask the guys who do not backup /home directory what is the worst case scenario they encountered after restoring the system? Or are there any problems at all?
I afraid that using the older application versions with newer configuration files and other stuff stored in /home may lead to problems when running restored version of Arch. My /home directory constantly grows so I have to make more and more exclusions or copying & symlinking folders to other locations to limit the backup size but I wonder if does it really worth taking notice of?

If you back up regularly, why would the application versions be that much older than the config files?
If you don't back up /home, worst case scenario is you lose all your data because you hadn't got a backup. It makes more sense to back up /home than any other directory (for desktop use, anyway).
