You don't need to modify dirvish to mail you. If you set up your cron 
jobs correctly you will get the output from them mailed to you.

In particular, it's quite clear from this output whenever a job has 
failed because of an rsync error. When you're checking the output daily 
you will know which is the last good backup, you won't need a pointer to it!

I just print the df in the cron job, so it gets mailed to me and I 
eyeball it every day. My mail messages are all backed up :)
