We have many SAN's deployed and they have their own problems with the drive 
persistancy issue.  We went away from SAN based backups and stayed with LAN 
with gigabit adapters and get the same performance.  As for the database 
edition, I am actually talking more than just databases.  We have large LUN 
file systems as well that require the same type of SLA's sometimes.  Some of 
these have database systems that there are no agents for and there is no 
other way around doing this.  I don't have a problem doing what is suggested 
below, but what I am looking for is cheaper hardware solutions than SAN's 
such as what ATL just came out with the DX-30.

Thanks,
Rick
