File flood or self-contained .gnucash file

[Alois Mahdal]

Hello,

I am using Dropbox to share my .gnucash file across multiple
hosts.  It's called one.gnucash.

Now I'd like to understand these things:

*   GnuCash seems to act quite strange regarding auto-save.Bu
    this I mean that each time it auto-saves, it actually
    creates backup of the old file, but does not seem to delete
    old backups (i.e. keep N older backups)

    Well, I appreciate it wants to keep integrity, but the
    files pile up; now I have about 50 files long update line.
    All named like one.gnucash.201301021234.gnucash

    Is this intended?  I'd normally expect to keep one or two
    copies, why 50+?  I could not find anything in settings
    apart from changing interval only.

*   With each of these files, additional .log file is saved.

    Do I need to keep these files as well?

*   In case I wanted to do backup other way, say using rsync,
    which files are recommended "to take on a desert isle"?

I'm using GnuCash 2.4.10, Debian Wheezy (both of the
machines) and for storage I chose gzipped XML.

Thanks,
aL.
