The reason why I'm asking this is that I have to "design" some backup
scenarios.  Each time there is a SAN and a (slower) LAN between 2 sites.  One
site is the primary site with the production servers, the other site is the
DR/test/acceptation site.  Somehow I have to backup servers on both sites and
do electronic vaulting.  Preferable no tape library.

I have some idea's, but none of them is good enough.  Right know, I'm doing
SAN based backups from the second site to the first site to a library.

The best setup I can find is setting up a TSM server on each site.  Each TSM
server can access SAN disks on it's own site and disks on the other site (for
copy stgp).  The only problem I see is monitoring the disk usage so I can
give each TSM what it needs.
Also, for the copy storage pool I need FILE based disk storage pools and that
means reclamation.  And reclamation on a remote SAN means lots of data
traffic.
