Hi,
the omnirc file you will copy to c:\program data\omniback for W2K8/W2012 Servers, to c:\program files\omniback for Windows 2003 Servers and to /opt/omni (as file .omnirc - note the leading dot) for Linux Servers.
My suggestion is to use one omnirc file which fits all. I at least use:
OB2INETTIMEOUT=10
OB2IPCNOSENDRECVLOOP=1
OB2SHMIPC=0
OB2IPCKEEPALIVE=1
OB2NOTREEWALK=1OB2INETTIMEOUT=10
OB2IPCKEEPALIVETIME=900
OB2IPCKEEPALIVEINTERVAL=60
You can copy the file to your Windows clients too, if you want to disable the first treewalk.
For making additional performance tests, I recommend:
- Run HP LTT Tools (with integrated hpreaddata and hpcreatedata) to test the performance of you disks.
- Use vbda process to test the performance of your clients - see http://www.data-protector.org/wordpress/2013/10/performance-test-disks-data-protector/
- Use a backup using a null device to test plain speed
- Use "omnispeed" to calculate MB/s for historic and current sessions - see http://www.data-protector.org/wordpress/?s=omnispeed
- Change the parameters of drives: Disk Agent Buffers: 16, Segment Size 10000, Block Size 512. The Concurrency (and if it is not a StoreOnce device) you set to a value where the tape becomes saturated. But keep in mind, multiplexing is fast during backup, but might become slow when doing restores.
So there is a lot more stuff you can try... keep posted.
Best regards
