transfer rate broke down to a third

Hello,
I know that this topic is stressed already some times in different variations, but I couldn't find any answer for me yet.

I do a full backup with BE 12.0 Rev 1364 of local Raid 5 discs to an internal RD1000 disc cartdrige. It's about 290GB in total. The BE job always runs at sunday night, no other job is running, no user is logged in.
Before this job had a transfer rate (order rate) between 1600 MB/min and 1800 MB/min, since three weeks the order rate broke down to 600-700 MB/min, what is getting time critical for me. It is the same server and the same datas backed up, so it can't be an issue of the numer of files or sizes and I didn't changed anything on the hardware.

The "only" thing I have changed in the order setup some time ago was to activate the advanced open file Option. But I thought it was before the break down of the transfer rate and I never heard, that it could affect the performance so bad.

I am thankful for every idea, what could have happened to my jobs or what to check for
thanks for any hint

  • Hi I just tested to make a B2D test backup on an internal HD and it run with blasting 3700 MB/min order rate
    So obviously it is related to the the RD1000 device, driver or whatever. I will give Dell a call.
    Thanks
