I noticed that SQL Server has a surprisingly large number of writes to \System Volume Information\{guid1}{guid2}
What is Sql Server doing when something like this happens?
In the above image half of my write IO for sqlsevr.exe is used for the System Volume Information writes.
This is being run in Windows 7 Profressional.
