Depending what OS you're running, you may have some cron script that 
specifically runs on the first of the month or as soon as practical 
afterwards (e.g. anacron, cron.monthly etc). You can run dirvish from 
such a script, with a different config file.

Another technique is to write a script that tests your monthly backup - 
perhaps just that it exists or perhaps some deeper test - and then runs 
dirvish if it doesn't exist. You can [try to] run that script every day.
