Dramatically slower backups with new LT05 SAS drive
While I am sure that this has been asked many times over, I cant find an answer that works.
I have BE 2012 Server Version 14.0, Rev 1798 (64 bit) runing on WinServer2008-R2 with 8GByte.
I had been running a Qualcomm LTO4 SCSI drive up until about 3 weeks ago, getting anywhere between 1500 and 1900 MB/Min speeds. My LTO4 drive failed and I replaced it with an HP-LTO5 SAS drive, and the best I can get out of it is approximately 600 Mb/min speeds. So what used to take 6hrs to back up, is now taking much more then over night, close to 18hrs, with Verify set.
The BE software was not reinstalled, I just deleted the old SCSI device, and add the SAS box. I let it install the Symantec-BE drivers.
I see many threads on the Drive devices properties in different ways. Can anyone share the location of best practices settings for my configuration?
Thanks to all in advance!
