It would be great to have the ability to automate MS SQL backups. I like the ability to be able to create a one-off backup but I think a really useful feature would be to schedule the backups, say once a day and be able to compress them and send them to an offsite storage like Azure or Amazon S3. An added bonus would be to be able to send a backup of the website filesystem as well.
We're investigating some third party off-site backup options that may be made available. We make backups ourselves for disaster recovery, and if you're ever in a pinch, we can often pull one of those for you. I understand that's not the same thing, but the data is all being backed up.
