Be2016 fails on Ex2016 - error V-79-57344-759

Hi Folks,

I had seen reference to this error in earlier posts, but as you see below, I tried and it didn't help. Hoping a new posting might gather some new insight? :-)

I am on BE2016, now with Exchange 2016...

I was getting 100% success rates with Exhange 2010, but now that we have migrated to Ex2016, I am also getting this old error. I have tried the DWORD mentioned in the other article (which I assume is NOT a typo in that there is a space in the DWORD name)... rebooted, ran another incremental, and the same error popped up.

(please advise if I should now remove the DWORD, or if it's safe to leave with BE2016/Ex2016)

Any thoughts? Or something I am missing?

Here is the exact text of the error:

October 25, 2017 12:23:48 AM - V-79-57344-759 - The backup selection '\\Crom.aquilonia.orb\Microsoft Information Store\Mailbox Database xxxx2' was not successfully processed for Granular Recovery Technology (GRT).

    Seeing this also. It was working fine a week ago. No updates as far as I know.  BE 16 fully patched, Exchange 2016.

    If I change it to Non-GRT, it backs up fine. If I change it back to GRT after a successful backup, it still fails again.

    Probably be opening a ticket next Monday. For now, everything is set to non-GRT.

      Thanks... always nice to know I'm not alone.

      Let's not open two tix, just let us know what you find out, ok?

      And, I'm not 100% sure the backup is failing to backup data, reads more like it's failing to verify the successful nature of a granular backup. Wondering if that simply means I have a good full database backup, but would be unable to restore a sinlge message somewhere... or... well, hard to say, with such cryptic error codes.

      Let us know what they say... ok? :-)

      (BE2016 is a new animal to me, so I'm not even sure how granular a restore it supports on Ex2016 anyhow)

        I'll let you know. If it's critical don't wait on me, BE issues can take weeks to resolve sometimes.

        I saw last nights backup finish, then it went to verify, got through 200GB of verify and I signed off. Came in this morning and it was failed. It does look like if I needed I could do a full database restore, but no GRT. Anywho, I'll post back.

         

        GRT with 2016 is good. You can select a single message and restore it right back into someones mailbox in a few clicks if you want. It's that granular. You want GRT to work.
