Hey friend!

Great question. Technically our backups can take backups of your docker volumes, if they are stored on the droplet's primary storage. Those, however, run weekly and not daily. The daily requirement alone means that nothing we offer as a service will satisfy it, and you would want to take other steps to accomplish it.

That said, I saw this really cool thing the other day and while I have not used it, you might find it equally interesting:

Personally I'm experimenting with rexray as a volume plugin to mount my volumes from a redundant object storage cluster (using Minio). I think what I'm doing with my own testing might be excessive for what it sounds like you need, but it has been quite fun.
