GnuCash - which data files to backup?

I am using gnucash and I am pretty happy with it but I have a question:  Which data files do I need to backup in order to be able to recreate my accounting data if I have a catastrophe?  Every time I hit the SAVE button, the program generates a lot of data files.  For instance, today I have 21 new files.  Some end in .log and some end in xac.  They have long redundant names like:




Perhaps I should back them all up, but it seems like there should be a certain file that holds all the data.

    Accepted Solution

    you basically need to save the .xac files and .log files
    .xac files contain the previous copy .. and .log contains the changes made

    so if you save only the .xac files you get the last backed up data.
