Hi,

We don't want to move tapes ... as little as possible.

We have about 1 TB of backups/archive data for about 60 nodes.
There is about 20 Gb of change every day (it must rapidly grow to 30 gb)

We have a second site available with an ATM link of 4 Mbit/s, we can upgrade
this
link up to 30 Mbit/s max. (it's only a matter of cost).

Best Regards,
Frederic Van De Velde.
