When running Data Protector 6.20 together with a media agent installed on Windows 2008 sometimes you might have a bad backup performance. Sure, this was a known problem when DP 6.20 was launched and it was fixed with patch DPWIN_00516. If you still experience bad backup performance I recommend to again read the description for patch DPWIN_00516; there are a new omnirc variable – OB2IPCNOSENDRECVLOOP=1. When doing backups over the LAN, in addition you should set variable OB2SHMIPC=0 gesetzt to further increase you backup speed.
