I get about 1GB/min going across copper Gigabit Ethernet, disk subsystems are from a U320 SCSI RAID5 to RAID5 SAS. I would guess the fastest D2D backups would be on the same server from one controller/disk set to a 2nd controller/disk set.

I've always liked backup to disk because restores can occur so much quicker when restoring a single file or two. However, the other day I was doing some testing and found that my backup to tape backups are a LOT faster than disk. Backing up 25GB of data to tape (LTO3) takes me about 25 minutes at 2,855MB/min. Backing up the same 25GB of data to disk takes about 2 hours at 460MB/min. Is this what most others are seeing, or is my disk backups just performing slow? -------------------------------------------------------------------- mail2web.com - Enhanced email for the mobile individual based on Microsoft(r) Exchange - http://link.mail2web.com/Personal/EnhancedEmail ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
