-# backing up all data older than $MONTHS months
-# Note: if set for example to 1, this will backup the overall month,
-# not only the records older than 30 days. This logic applies generally,
-# so it will go back $MONTHS months, and starting from there, backing up
-# the full months back to $MONTHS_BACK
-MONTHS=3
-# from the starting month above, also go back $MONTHS_BACK months and
-# backup them
-MONTHS_BACK=6

-# archive tables older than $ARCHIVE_MONTHS will be dumped to a file,
-# gzipped and then dropped afterwards
