Vista client - what is this file?


Recommended Posts

When backing up a Vista client I notice that a huge file with a name of the format

{lots of random characters}-{lots of random characters} is backed up. This file also seems to compress incredibly well as the data transfer rate goes up by a huge amount (such a large increase that I don't quite believe it and maybe its not down to compression but something else).


Can anyone shed any light on what this file is, and whether it even needs backing up.

I believe that these files are in the "System Volume Information" folder and are part of System Restore the tool that allows you to set points in time to roll back your computer. I cannot imagine why it needs to be backed up but I have been unable to exclude it from backup on my system.
