SuperDLT vs Ultrium

[Pocket]

Hi,

We're looking at some new tape technologies for a replacement backup solution. We've narrowed it down to Ultrium or SuperDLT, and are trying to decide which one best suits our requirements.

If anyone has any thoughts/experiences/opinions they'd like to share with me regarding these two formats, I'd really appreciate it.

SDLT I have no experience with, but LTO I do.

I have 2 Ultrium drives (100/200GB). One is a Qualstar library, the other is an IBM standalone.

We consistently see 14-20MB/second backups (depending on the speed of the server backing up the data), however we are backing up 220GB in "little" chunks of 1.9G. Your backup speed will decrease substantially if you have many small files.

Tape reliability is critical - don't get cheap tapes. Sometimes we do (I don't have too much say so there) and we pay for it.

I think their web site is

http://www.lto.org.

LTO is set for 4 generations, with the 4th being 800GB capacity, with a 80-160MB/s transfer rate.

Hope this helps!

Bill.

We've had great success with LTO - can't speak to DLT as I've never used it, we jumped straight from DAT to LTO. I use a single HP drive in HP's 5500 rack enclosure. Our results are similar to bjverzal's.
