We here at Curious System Solutions use dreamhost as our hosting provider. One of the nice things they give us is a nice, tidy, backup every month, if we ask for it. It may take a few days if you ask at the beginning of the month, and it is easy to forget to download. So, we have a handy python script that will check an imap4 email server to see if the backup is ready, and if so, download it. The script is designed to be a cron job that can be ran every night so you don\’t have to worry about remembering to download things.
