Multiple backends for snapshots

The snapshot feature of django-sql-explorer is a very nice and convenient one. However, I think it would be even more convenient to have more options than Amazon S3, which is a non-open source commercial solution, to store and retrieve these snapshots. For instance, I would be happy to be able to schedule snapshots on the local filesystem, or send then in a self hosted storage server. I don't think it is a difficult feature to implement, what do you think? I'll try to do it myself if I have the time for it!
