Hi All,
I just installed Backup exec 2014. Tape backup is too slow, it spends too much time before the IO running.
----------------------------------------------------------------------------------------
Windows server 2012 R2 Datacenter
Backu Exec 2014
VTL IBM TS3500
IBM xxx Fxxx LPe1205A-IBM 8Gb 2-port Fibre Channel Adapter
-----------------------------------------------------------------------------------------
1.One job (1 file 5G) takes about 15min;
Two jobs (both 1 file 5G) takes about 25min;
One job (30 files total 150G) takes about 45min;
30 jobs (5G each, 150G in total) takes about 3hours.
2.The actual IO rate is about 50M/s which is reasonable. It just spend too much time before the IO running. And the time increase while the jobs increase.
3.Restore performance is good.
Do you have any insights?
Many thanks!!!!!

Hi,
Are you using the Symantec drivers for the tape drive?
If not, try them and see if there is any sort of impact.
Thanks!

Is this option "Display progress indicators for backup jobs. This requires additional time to pre-scan resource." enabled under Configuration Settings - Preferences ? if yes, disable it and check if this makes a difference or not.

Hi CraigV,
Thank you for your quickly repley. The following is picked in tech doc. There is no need to install tapeinste.exe in windows 2012R2.
"Note: You do not need to install Symantec tape device drivers if Backup Exec
runs on Windows Server 2012 and later. Symantec kernel-mode drivers and
tapeinste.exe are no longer installed if Backup Exec runs on Windows Server
2012 and later."
