Atomic backup with NFS backend?

[lukemarsden]

Hey folks, Convoy looks really cool, nice work!

I see you have an NFS backend, and support snapshots. But are NFS-backed volume snapshots atomic, i.e. safe for crash-consistent databases? If so, how does this work?

Separately, I'm interested in discussing how it would make sense to integrate Convoy as a Flocker backend.

Thank you @lukemarsden !

NFS snapshots are only tar balls. We added NFS mostly for distributed filesystem. Device mapper would do a much better job at quickly taking crash-consistent snapshot and doing incremental backups.

We're also interested in how to integrate with Flocker. Please feel free to shoot us emails!
