SuperDuper and XSan

[tcmcam]

Can I use SuperDuper to clone an XSan volume?

We've got a 4TB XSan volume that we are copying to a 4TB external eSATA device.

They both show up as Volumes to OS X, but I don't know if that means SuperDuper supports them.

Doesn't SuperDuper use ditto under the covers (in addition to other commands)?

Shouldn't this be a safe operation to run a SmartUpdate?

Thanks!
