Hello Stephen,

For backup, I run "bogoutil -d" as a nightly cronjob and then keep a
week's worth of the resulting text files.  That provides extra security
in case something goes wrong while I'm off-site for a few days.

The count going to zero could be caused by database corruption that
resulted in the loss of the .MSG_COUNT token.  If "bogoutil -d" doesn't
show the end of the alphabet then your database got truncated.

HTH,

David
