DPM 2012 SP1 Wont Syncronize my Disconnected Clients

    Question

  • I backup data from a few different servers.  Those all work fine.  However, none of my Laptops are backing up and from what I can tell it's because there are no sync jobs running.

    For all my servers (once a day) I see a sync job then a recovery point job.  For my laptops I only see a recovery point job that says:

    "No recovery point was created, either because synchronization has not occurred since the last recovery point was created, or because no changes were found during synchronization. (ID 208)"

    There are in fact changes so these missing sync jobs seem to be the problem.  How can I get these protection groups to start syncing again?

    I can run Create Recovery Point manually and select Create a Recovery Point After Synchronizing and it works fine (once).  So it "can" work.  I just don't know why it's not automating the sync part because it goes right back to not creating any new Recovery Points.

    Many thanks for any help!

  • So...blowing out the PG's didn't do any good.  I blew them out and blew out the VHD's holding all the data.  Set everything up again and even blew out a select few of the agents.  Nothing worked.

    Removed all agents.  Blew out the entire server.  Set everything up again from scratch.  Everything works fine.

    I'm getting a little sick and tired of that usually being the only solution but I guess that's our IT life these days.

    Thanks again for all the help Mike, I appreciate it.

  • Hi,

    You will not see scheduled synchronization jobs for client protection because the clients initiate the syncs when they are online and connected to the network. If you logon to a protected client and open the dpm agent you should see the last successful sync and have the ability to initiate a manual sync which should show as a running sync job on the dpm server.

  • My laptops used to sync on their own just fine.  All my laptops at this point in time are online and none of them are backing up.

    Looking at the client side they all say Last successful Synchronization: 19 days ago+....that would be the last time I manually ran it from the server.

    They also say Synchronization Schedule: Every 24 hours.

    Those are the jobs I'm talking about.  All of a sudden none of my clients are running that sync job therefore I am not seeing it on the server.  It shows up under jobs even for disconnected clients.....when it actually runs.

    Why would 100% of all of my disconnected clients no longer run this job every 24 hours like they are told to do?

  • Hi,

    If you initiate a manual sync from the client - does that succeed ?

    Make sure you are running the latest DPM 2012 SP1 UR5 update and the clients agents are updated.

  • If I run it manually on the laptop it seems to run (hourglass on the DPM icon, says synchronizing) however after it's done it still claims to have been last synced over 20 days ago.  I see nothing new in Application or System Event Logs.  Is there some other log that it posts to?

    If I run Create Recovery Point after Synchronizing from the DPM server then the client reports that it was last Synced xx Minutes ago.

    I'm on DPM 2012 SP1 v4.1.3426.  All clients are up to date.  In fact, some of these laptops are brand new.

    So at this point, I can only back them up if I run it manually from the DPM server.  Sync will not run right from the clients....100% of them.

  • Hi,

    1) On one of the client machines, open an administrative command prompt.

    2) CD to C:\Program Files\Microsoft Data Protection Manager\DPM\Temp

    3) type: find /i "TriggerBackupForClient" DPMCLIENTPROTECTIONCURR.ERRLOG

    This will list the attempts to make a backup.  The frequency of the log entries should match the synchronization frequency of the protection group + 15 minutes.   So Every 24hrs+15 minutes In your case.

    Now you can look at the backup job details in the DPMRACurr.errlog that matches the start time from the entry in the DPMCLIENTPROTECTIONCURR.ERRLOG.

  • Thanks for sticking with me Mike!  I greatly appreciate it!

    The last entry in DPMClientProtectionCurr.errlog (for TriggerBackupForClient) is:

    22:10:23.434 - TriggerBackupForClient - ClientMachineName: <MACHINE NAME>, ForceFixup: False , IPList: 169.254.254.77;169.254.98.67;169.254.254.177;169.254.36.206;10.10.10.43;fe80:0000:0000:0000:0000:5efe:0a0a:0a2b;

    Two issues with that:

    1. What's up with the 169.254 IPs?

    2. The last entry in DPMRACurr.errlog was at 21:52:54.705...there is nothing at the same time as above.

    Also, TriggerBackupForClient is running every 20-30 minutes.  The log file is huge and there are multiple copies of the file that go back even further in time....DPMClientProtection0.errlog....

    Scanning through DPMRACurr.errlog I'm seeing a whole lot of:

    0D88    06E8    03/13    15:57:08.102    18    fsutils.cpp(3224)        0CC66FDC-3C3D-4D52-822C-1F559309A74D    WARNING    Failed: Hr: = [0x80070057] : GetFileHandleById failed to open file, frn:0x0011000000001203

    Nothing else really stands out.

  • Hi,

    I'm not sure about the goofy IP's - but don't think it's related to the issue because mine are also the same.

    The times in the logs are GMT adjusted for daylight savings.  So pacific time zone would show times in the log as local time +7 hours.

    For every triggerbackupForCleint entry in the DPMClientProtectionCurr.errlog there should be a companion entry in the DPMRACurr.errlog that should initiate a local snapshot of the volume(s) that we're protecting data on.

    See if you can find these entries.

    find /i "createsnapshotsubtask.cpp" dpmracurr.errlog

  • Of the thousands of entries for TriggerBackupForClient, I only found 1 entry for createsnapshotsubtask.cpp way back on 2/10:

  • Hi,

    OK - this is probably something that cannot be troubleshot in a forum setting - please open a support ticket for a DPM engineer to assist.

  • I checked a few other logs and some of them don't have createsnapshotsubtask.cpp at all.

    I'm afraid I wont be taking that route.  I've been down that road before.  I'd rather blow out the entire machine and set it up from scratch since it makes absolutely zero sense that the problem is on the client side since it's 100% of all my clients.  I'll start by blowing out the entire protection group for the laptops and setting that up from scratch first.

    If there's no actual answer for this then that's that.

    I greatly appreciate the time you've spent on this Mike!  I'll report back if the PG in general was the issue.
