Good Morning.
We are currently getting around 650MB/min when duplicating any job to our direct connect Dell PowerVault 124T LTO4 Tape Drive.
Any ideas if this is a good speed or how we can improve it?
Thanks
Lee

Could be why you're getting slow performance. The data needs to be rehydrated/reconstructed when going from dedupe folder to tape.
You can try to tweak your tape drive to see if you can wring a bit more performance out of it. Check a good article by pkh out on the link below:

What are you duplicating from? Dedupe folder or normal B2D? If dedupe, you would facotr in that it is rehydrating your data when going to tape, so it might actually be a good speed then.
Thanks!

Hi Craig,
Yeah the data is going from DeDuplication SAN storage to LTO4 TAPE.
