Kind of a work around but if you are running in windows environment create a scheduled task that runs weekly that executes a batch file that zips the file then either emails it or ftps it somewhere. something like
if "%time:~0,1%"==" " set HH=0%HH:~1,1%
alzip -a "C:\program files\dude", "c:\backups\dude%YYYYMMDD_HHMMSS%.zip"
You could then extend the script to copy it to another server or ftp it to a server
