Consistency Checks Re-Copies Files RRS feed

  • Question

  • Hi everyone - I have an interesting issue.  I have been seeing an issue on a few of my protected servers where DPM 2007 re-writes files that already exist on the dpm server and they have not been modified.  This happens only during consistency checks.

    For example, I watched it re-write (using task manager) during a con check a .SID file with a modified date of 9/21/2005, accessesed date 9/10/2009 and created date 9/5/2008.  The file is over 3GB and there are many of these type of files.  The files do NOT have any ntfs compression on them. 

    It is currently running a con check and has written over 126GB so far and has been running for days.  Most of these files have not been touched in a while.  I'm not sure if there is some sort of compression within the files that is causing DPM to re-write them everytime a con check is kicked off.  Has anyone seen this issue before and know of a resolution?

  • Hey,

    Yes, we have seen this issue before.

    It happens when AV (for example) runs and does things with the files or it also happens if the file has some sort of encryption on it, making it impossible for the VSS writer to verify and therefore does the backup again.

    I have no idea what the .SID files are, but most of the time I would be looking at your AV solution.  Try to change your AV so that these files are excluded (as a test...) and see if DPM still has issues.

    Just my 2 cents

  • Thank you.  I was thinking it could be related to AV too.  I will test that out.
