I can back up just about twice as fast to an SAS LTO4 tape than I can to an ISCSI raid array, both being attached to the same media server. ----- Original Message ----- From: jesse-rink@ wi . rr .com To: "NT System Admin Issues" < ntsysadmin @ lyris .sunbelt-software.com> Sent: Friday, November 14, 2008 10:12:49 AM GMT -05:00 US/Canada Eastern Subject: tape/disk speed
I've been doing backup to disk backups and backup to tape backups for a long time. 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® 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/> ~
