every day Domain Controller backup reports some warnings about these files:


They are always locked by some process and Data Protector could not backup them. As I backup the System State too, is it safe to set an excepion on these files for file system backup? Can I exclude the whole ntfrs and security folders?

Thank you all for help!

Those the the Windows registry database files, so they are always open (as long as Windows is running). Backing up the registry through the proper utilities/facilities (e.g. ERD) will take care of any information you need to protect there.

This is partially incorrect, WINDOWS\ntfrs is related to the File Replication Service while WINDOWS\security seems to be related to Windows Security files, they are not registry databases. I agree about windows keeps opens these files but the question is if they are part of the system state or not. – Danilo Brambilla Aug 2 '12 at 15:24
