SRTSP events on client

Hi,  

We are running on SEP 12.1 RU 1 MP 1, on a winows 2008 with SQL DB.

one of my client ( server 2008) shows an event " Event : File System Filter 'SRTSP' (6.1, ‎2012‎-‎03‎-‎01T11:44:25.000000000Z) has successfully loaded and registered with Filter Manager." , 

After serching we come to know that SRTSP is related to auto protect, can any one guide me what is the exact event tell about?

Regards
