DBacked is a command-line tool and SaaS product that creates, encrypts and stores backups of your MySQL, PostgreSQL or MongoDB database. It monitors your backups and sends you an email if a problem is detected. The CLI tool is open-source and free to use with your own S3 bucket.
Open source and extremely optimized
Can't think of anything
It just works! And the fact that it's open source is awesome. The way it works is pretty amazing too: the database dump, encryption, compression and upload is all done in memory…Matthieu Napoli has used this product for one month.
Automating a problem I'd rather not think about
Pre-compiled binaries inside "open source" agent, MD5 used for backup integrity
While I have no reason to doubt the binaries embedded inside the agent (pg_dump, mysqldump and mongodump) are legitimate, I have no way of auditing them either. Additionally these binaries and their integrity checking is controlled by dbacked's servers, meaning they can be swapped arbitrarily at any time (by themselves or an attacker). I would need to see their source for these binaries, and a way of pinning which version I am using before I could seriously consider this product from a security perspective.James Cunningham has never used this product.
