Clarification please, Re: DPM 2012 and Reparse points RRS feed

  • Question

  • When modifying a protection group in dpm 2012sp1, on the final screen is a message stating that dpm doesn't protect reparse points.

    DPM does not protect reparse points found in file systems, except for deduplication reparse points, which are protected.  If you have selected volumes or folders in this protection group, all data is protected except for the unprotected reparse points. 

    However, the documentation on technet here seems to disagree:

    When you select a data source that contains a reparse point (mount points and junction points are data sources that contain reparse points), DPM prompts you to specify whether you want to include the target of the reparse point in the protection group. The reparse point itself is not replicated; you must manually re-create the reparse point when you recover the data. 

    Which is correct?

    If I create a hard link (or symbolic link, junction point, etc) to a file located on the same drive, and create a protection group which includes the hard link, should I expect DPM to back up the linked file?  I've tried doing this, but am never getting a prompt asking about whether to back up the target of the reparse point, as the technet page says I should.

  • Hi,

    This is a list of unsupported data types:

    When you have mounted volumes in the root of a volume, and you select that volume to be protected, DPM will popup a message asking if you want to protect the underlying mounted volumes.  It does not do that if the mountpoints are deeper in the directory structure. So you need to be aware of that.

  • Okay, so has nothing actually changed in the processing of reparse points between DPM 2010 and 2012/2012SP1, other than the support for deduplication?

    Thanks!

  • Hi,

    That is correct, there are no differences between DPM 2010 and DPM 2012 Sp1 with regards to handling protection of unsupported file types and mountpoints.

    The only exception is the below issue is now fixed and no need for the workaround.
