I should be more specific. We'll looking for a storage/sync solution, and not disaster recovery. We don't have the bandwidth for disaster recovery.
What we are tying to do is have a cloud drive where we can have up-to-the-minute syncing between multiple computer (not at the same location).
Our first hunch was Google Drive, but it doesn't like it when a folder that you're trying to sync is on the network, and not the local drive.
