IF you are using SQLite as the database engine, the digikam databases are 
three ordinary files:
- digikam4.db
- recognition.db
- thumbnails-digikam.db
These can be copied like any other file. 
To be safe, I make sure I have no Digikam running when backing up the files 
(not sure what happens if one if the databases is changed during file copy, and 
I'd rather not find out the hard way).
