Sounds about right, I am getting 1,500MB/MIN (25MB/SEC) on my backups. And iirc my restores were about 20MB/Sec going to bare metal RAID5.
What speeds do you see with LTO? Has the reliability of tapes increased in your opinion? Good info, thanks as always.

I've generally found that USB2 peaks at around 15-20MB/sec, and eSATA is around 25-30MB/sec (max) With LTO4 - if you are copying from a single disk, then the limitation will be the source, not the destination. Likewise with restores, you'll probably be bottlenecked by the target if it's a single spindle.

Had no idea. I've been on eSATA drives for years now, ditched tapes for the speed and reliability. Ken, do the restore speeds also show this type of performance? Because ultimately that's what matters, right. -----Original Message----- From: Ken Schaefer [mailto:k...@adopenstatic.com] Sent: Tuesday, September 15, 2009 10:36 PM To: NT System Admin Issues Subject: RE: Disk based backup USB connected drives are way too slow. LTO4 alone should get you 5x-6x the speed of a USB connected drive (YMMV) Cheers Ken -----Original Message----- From: Benjamin Zachary - Lists [mailto:li...@levelfive.us] Sent: Wednesday, 16 September 2009 9:14 AM To: NT System Admin Issues Subject: RE: Disk based backup Why not just take some external drives and mount them in whatever you use (BEX/UB etc) and rotate the drives. At 79 bucks for a 1TB SATA, or 89 for a USB version, you could do a 5 day rotation for 2 weeks for 900 dollars if you can get the data on 1tb. If you want to be more involved do the backups with deltas so you only do changes throughout the week and should be good. With the drives being so fast restoring through 3-4 usb drives isn't really a big deal, not like waiting 30 mins for cataloging a tape.. ~ 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/> ~ ~ 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/> ~
