You could also look at san snapshots too , if you have an iscsi appliance or similar. You can get full snapshots in just a few minutes of terabytes, but then you still have to get that to tape.
The way we used to do it before d2d2t was to put 2nd nics, and switch between the backup server and servers. On their own subnet and nic we could get full throughput and backup without affecting a lot of performance within the network. The i/o of the disks could usually handle it, and obviously sql/exchange aware backups can run in real time.

We do do some D2D prior to tape for our VM image back ups. We should look at possibly doing more of that.

The LTO loader my client has does about 1gb/min. From: Matthew Carpenter [mailto:[EMAIL PROTECTED] Sent: Thursday, January 10, 2008 10:41 AM To: NT System Admin Issues Subject: Back Up Best Practices What is the latest recommendation on back up processes? We have been small enough to do full back ups daily for some time, but now face time issues with that and need to move to a tiered option. Is F-I-I-I-I reasonable anymore or is it too risky? I do not want to be stuck with a bad full back up in an emergency. -- http://www.otbdesign.com http://www.linkedin.com/in/mqcarpenter -- http://www.otbdesign.com http://www.linkedin.com/in/mqcarpenter ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
