Doing a database snapshot (ie. maintaining consistency) for backup purposes requires some sort of add-on for most SQL databases -- if you keep the db server running during the backup. Most of these add-ons cost real money.
But you can build them with open source SQL software, and all you're doing is paying the dev for his/her time, as opposed to Dev time + hefty licensing fees.--
