Instructions

For anti-virus software, disable scanning of the NetWorker databases. If the anti-virus software scans the /nsr folder, performance degradation, time-outs, or NetWorker database corruption can occur because of frequent file open/close requests. The anti-virus exclude list should also include NetWorker storage node locations that are used for Advanced File Type Device (AFTD).

Disabled anti-virus scanning of specific locations might be ineffective if it includes all locations during file access, despite the exclude list, and skips previously accessed files. 

The nsr directory exists on all hosts where the NetWorker server, storage node, or client software is installed. It can be found under:
Windows: [NetWorker Install Path]\nsr
Linux: /nsr

NOTE: On Windows, the install path is specified by the user/admin during installation; however, if this value is not changed the default location is C:\Program Files\EMC NetWorker.
