Multiple protection groups for a single datasource RRS feed

  • Question

  • Dear ,

    i have DPM2016 with rollup2. i have a server where where all the shared files are putting there. on this server i've mapped a 76 TB from a dell storage.the shared folders on this partition have a size of 3.5 TB. i created a protection group to backup these shared parallel i am running backup exec to have a double copy. after a recovery point the protection group start a consistency check. the consistency check is taking around 38 hours to be done. the protection group gives me a green ok after that a recovery point occur according to the schedule and then a consistency check and so on. 

    my question is can i create multiple protection groups for the same data source (for example D drive). other question why is this happening why every time the protection group run a consistency check.

    Once a data source is protected it cannot be protected again.  You need to look at the failed synchronization job and alert details for actions to help solve.

    I suspect the USN Journal is too small on the protected server.

    Increasing the size of the NTFS Change Journal

    fsutil usn createjournal m=4294967296  a=536870912 X:   (where X: is the drive letter of the problematic volume)
