Did anyone get a DroboShare to work reliably?

[jrychter]

I've tried sparse bundles and sparse images, in both cases things fail in various and mysterious ways, e.g. various errors, DroboShare going away, etc. I've seen my Drobo volume get mounted twice by DroboShare (!).

In any case, I am unable to perform reliable backups to the DroboShare.

If not bundles and sparse images, what do people use?

And I wonder — why would SMB cause problems for sparse bundles? I thought they might actually be easier to handle, because of being split into 8MB bands.
