  One more thing, Data Domain's support has been outstanding.

It does work, and it works great!!
I can highly recommend the DataDomain DD200 retsore appliance.

it is easy to configure and integrate with the backup (be it Veritas,
or Legato ;-) (just a NFS or CIFS mount on your backup server), then
the backup system writes the image files onto the datadomain.

I do achieve a global compression of currently 18, have seen already
higher compression (varies depending on data of course).

I only wished the system was a little bit bigger ;-) and a little bit
faster ;-), although I do actually achieve the same throughput as an
S-AIT drive, up to 32 MByte/sec so far...  Restores will be faster
though.  No waiting for tapes to be mounted, data is raid protected,
can be replicated to another DD200, (or vaulted to tape), easy to
manage, great system.

Cheers
