    Hello David,
    Thanks a lot for your persistence and your help,
    Actually we found the root cause of the problem, it was a problem in Reverse DNS (media->master) once we corrected that, backups start to work again.

My reading of the logs is indicating a problem in taking the snapshot. As such I would review the VSS status of the server to see if there are issues there.

Secondly, is there any reason for leaving the NBU client at an unsupported version (7.6.x)? You are running an unsupported configuration and there seems top be no reason why this server couldn't have a more current client installed.

Is this a fresh issue or something that has been around for some time?

Hello David,

Thank you for your reply,

I actually suspected that could be a vss problem but I didn’t find anything abnormal on this side, besides, I enabled bpfis bpbkar bpcd and vnetd logs on client and when I run the backup I don’t have logs on the client, only vnetd and bpcd when I try bptestbpcd commands which lead that the problem is on the media or master server( I suspect it is on media server but can’t figure it out..)
And actually I thought about upgrading netbackup version but as mentioned we have the same problem on some clients in higher version (8.0)..
And no this is not a fresh install.. it used to work fine before and suddenly stopped (no
Change were made..)

    Can you share the admin logs from the media server?

    And the bpcd & vnetd logs from the client (and if anything else is logged as part of the backup that too).

      Hello David,

      sorry for the delay , I had to ask our customer for these logs..

      for admin logs on media server, I enabled them and there are no record of the job that I run, only in bpbrm ( attached to this reply)

      same thing for bpcd & vnetd logs, nothing is in there, I don't think there is any connection to the client to initiate the backup.. which is confusing..

      I attached a snip of bpbrm log & detailled status (for the time stamp)

       

      thanks again for your help

        The one thing that sticks out (and I noticed before) is that the time doesn't match between what is displayed in the activity monitor and the time in the bpbrm log. In particular this looks problematic:

        14:53:52.464 [1796.1796] <2> get_long_base: (2) premature end of file (byte 1)
        14:53:52.465 [1796.1796] <2> job_connect: Can't get server time
        14:53:52.465 [1796.1796] <2> check_connect_time: It took 1 seconds to connect.
        14:53:52.465 [1796.1796] <2> check_connect_time: Giving up trying to connect. Function elapsed time (301) > client connect timeout (300).
        14:53:52.465 [1796.1796] <16> event_msg_to_monitor: failed to connect to bpjobd on master server SRV-MASTER.domain.com (23)

        While in the job details the time is way different:
        Sep 2, 2020 3:38:44 PM - started process bpbrm (pid=1796)

        It's possible fixing the time mismatch may solve your problems.
