Much more (> double) than TSM last time I bothered to ask. But that
was for _our_ setting. Prices for any backup systems can be based on
any measure that some pointed hair boss has figured out (petabytes,
tapeslots, cores, clients, moonphases, you-get-my-drift) so you really
do not know before you have asked and haggled about the price etc etc.
It's like at the oriental bazaar.

I think backing up without snapshot functionality is a bad idea as the
contents will otherwise not be consitent.

To do a restore, you would need to convince the fileserver/volserver that
a vos restore has happened under their feet. You could of course for
every restore start a new server and then vos move the restored contents
from there. You are moving to untested terrain here.
