In addition to this I would recommend backing up /etc in the same way,
in order to have a backup of all your system wide settings. Now you may
also find that you have data in /var too. MySQL and Postgresql databases
will likely be in there, and if you are using some kind of local IMAP or
squirrelmail thing for mail your mail *might* be in there too. Without
knowing exactly how you are using your machine, and what software you
are using, it's hard to say for certain whether backing up /home is
sufficient.
