Well, yes. I would. Except it's a storage appliance, not a generic
server. I get a choice of NFS, CIFS, or direct-exported blocks In this
case, it's actually an Oracle ZFS-based appliance, which is Solaris
under the covers, but I'm guessing it's going to be difficult to get the
bacula-fd running there. And they're claiming that doing stuff at that
level, will potentially void warranties.
And that's actually an improvement. The system that this is replacing,
is a bunch of embedded FPGAs that serve NFS. No OS that I get to see at
all. Whatever OS there is, is completely hidden, and likely very custom.

Ah. That's a good clarification. So it will only traverse to a new FS,
if the new FS is mounted in the tree where the backup is occurring?
That's dramatically less likely to happen.
Now if I can figure out a good way to mount everything I need, or
alternatively use an external file or script to define it, I might be in
business.
