Priceless, A windows machine getting better throughput via NFS to a Linux Server versus a Linux Host? What Server/Linux Host? Mount options, bad NFS Kernel (Recent RHEL debacle finally just resolved)...
Remember that Google suggestion :) http://support.microsoft.com/kb/929110 /snip This problem occurs because a problem in the original .NET Framework 2.0 Setup sets the value of the HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\ dword:ObCaseInsensitive registry key to 1. The HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\ dword:ObCaseInsensitive registry key determines whether a file system is case sensitive or case insensitive. If the value of this key is set to 1, the file system is treated as case insensitive. If the value of this key is set to 0, the file system is treated as case sensitive. /snip I would research the ramifications of this tweak, and if you have a Linux Backup License/Agent for your ware I would most certainly tune your mount and avoid this super messy conundrum! How are you handling perms etc in your backup?

I have been given more accurate info and I was a bit wrong of the assumptions. The main issue is that backing up from the Windows machine the NFS export (as local filesystem) from Netbackup is causing that anything case sensitive written from POSIX machines (Unix/Linux) is just considered as just one file. Backing up such exported NFS filesystem from a Linux machine takes 4 times more (40 MB/s vs 8 MB/s) Can you point me to documents of such Windows kernel tuning? We are wondering if changing something in the OS level could change the behavior of Netbackup running on Windows and performing restores case sensitive. This makes sense?
