We have been running 430's in pilot between Hong Kong, Atlanta, and DC specifically testing the replication piece. It works very well, and is effectively allowing us to go tapeless. We will still roll off monthly or quarterly backups to tape for archiving/long-term storage.
With the incredible results we've seen so far with de-duplication and compression, we expect to be able to keep at least 90 days of backups online. We are currently averaging 25 to 1 compression on the boxes that have been running for the last 90 days. We have also seen our backup windows drop down to a fraction of when we were running to tape (DLT IV and LTO 1). In one of our sites, with ~100GB of Exchange data, the backup time went from just over 11 hours down to less than 1 hour. We have seen similar results on restore times. I did not think BackupExec was capable of that kind of performance. We will be receiving (3) 460's and (6) 410's this week for our remaining offices to replace our current tape libraries. My backup guys can't wait to get these configured and in place.

Use it to store all SQL, Oracle dumps, Exchange 2003 and as a disk unit via Netbackup as well. We're seeing about 12.5x compression for our Exchange backups. The cost of the storage alone was well worth the buy for us but having that capacity optimization allows us to retain up to 30 days on disk for quick restores is huge. Performance of the unit allows us to drive our tape drives adequately and reduced the shoe shining effect that we've previously seen when backing up from media server directly to tape. Can't wait to test out logical replication built into the product over the WAN.
