It depends. You can configure where digikam stores the internal database 
files. If you used your home directory for this it is all you need to 
backup (besides your photos of course). If your photos are stored on 
your home directory as well, you are almost done. Just make sure, your 
path name does not change (or create a symlink) and on it goes.

Using a external drive is one way. If you store your digikam database on 
the external drive as well this is ok. If you store the database on your 
home drive, you will lose all tags and additional information not stored 
in the photos itself (either because you have not done it, or because it 
is not possible - tags can not be stored in canon raw files).

I am not sure, how digikam handles extension to database layout in newer 
versions. If you try a new versions, the database may change in an 
incompatible way, so that an old digikam version is no longer able to 
read it. But this is wild guessing.
