While working on a recent Rails project, I wanted to occasionally backup the database to a remote location. Since we were already using Subversion for source control, I figured I could just use it for storing the DB contents as well and came up with a short Ruby script for this, called dbbackup (ironically, stored on a Git repo – I guess it could use a –use-git option ;)
The only Rails tie is that it uses config/database.yml to get the database name and login info, so you could easily adapt it to run on non-Rails projects too. It’s built so that it can be ran by a nightly cron task, and since it’s only sending the diffs it wouldn’t be too resource-heavy.
I wouldn’t use this for Facebook’s production servers, but if your needs are more moderate you might find it useful. Feel free to send over any questions or patches to niryariv@gmail.com. Here’s the repo URL again, with the script and an explanation on how to use it: http://github.com/niryariv/dbbackup/tree/master
