More importantly, even if you do a daily backup make sure you have multiple levels of backups. You could get a hacker in over time, they are normally very patient. If you do not have backups offsite also, you are playing with fire. I do a daily full backup of both servers but also email just the necessary characters tables to a separate gmail account, I developed a script to do this a long time ago. If a hacker gets to my compressed backups, at least the email backups are out there and I could recreate the server from that. In the future I would also like to add a removable backup to the server as a last resort or maybe something that will do a block level copy of the vSphere host, but that will have to come after tax season
Does anyone know if you can email files to a Dropbox account? That would also be a another great level to backing up, you could shoot just the character level SQL's over to a Dropbox, a third layer of protection.
