  • Hi,

    Check to see if the drivers you have installed are optimal - also there are a couple registry settings that should help.

    Please review this BLOG and see if that helps.

  • Hi,

    We have similar issues with Dell TL4000 with 2 x LTO6 SAS Drives.

    Under Windows Server 2008R2 and SCDPM 2012SP1 with drivers

    Title: Tape Automation: TL2000/4000 Driver
    Version: A10
    OEM Name:
    OEM Version:

    We used to have a consistent tape backup rate of 400-450 Gigabytes per hour.

    After upgrading to Windows Server 2012R2 we are experiencing much slower speeds. The job can start with 400GB/h and then slow down to 200GB/h or even 100GB/h then speed up to 400 again. On average it performs 2 times slower then same hardware under Windows Server 2008R2. 

    I have tried driver version and also latest no difference.

    A good indication is the folder with 4TB of very large files  located on Dell MD1220 SAS enclosure connected to the backup server via Dell H800 Raid card.  We backup this folder every weekend to tapes. Before upgrade to Windows Server 2012R2 this job used to take 8.5-9hours, never longer than that, and now under 2012R2 it takes between 19 and 23hours.

    Very strange.
