    Local and remote safety copies are both set to '1' in my case.

    Certainly if you can connect to your HCP's, pause your archiving, and then watch the item counters, the replicas will be at least five minutes before it catches up and all data is replicated, and in my case, they always end up identical and no errors shown at all.

    If you DTrace this, you'll see entries such as this, 50 of them for each partition you look at before it gives up and chucks an error out to the event log:

    <6376>  EV:M     Hitachi Content Platform (HCP) Streamer: ConnectionManager::Set_Curl_Operation method http://sev.hcp01.company.domain.com/rest/evj/FE3B6887064C84499BDC21188669B190/2013/Dec/19/38b804ff-efad-44d8-9c97-25fba74fcd1f/00_00_06/00461 Reason = 404 : Not Found - opr_HEAD
     

    If you can get hold of the Hitachi migration tool, you can connect to the file system and go and have a look and just check that the data is present on the replica, in my case after looking at this over and over, I can't find anything wrong and the events logged, whilst alarming and no doubt going to upset and confuse, seem at this point to be harmless information and a bit of a red herring, but I have thus far been unable to have that confirmed

    Hi,

     

    i would like to confirm that setting Local and remote safety copies both  to '1'  resolved problems regarding Saveset not being backed up error.

    It's strange that by default this setting is 2 and i think it should be 1 :)

     

    Regards.

This was interesting to read just now, I have the same configuration at my customer, I see the exact same messages, they can appear at random during the day, but always appear after you take EV out of backup mode. 

Event ID: 28967

"Watch file partition scan will be stopped for the following partition since 50 consecutive unsecured (not replicated or backed up) files/streams were found."

I have access to both HCP's, production and replica, I placed EV tasks into report mode to allow it to process everything without adding any new items, I had a look at both HCP's and each showed identical item counts after a few minutes to allow replication to complete. From the EV side, all unsecured item counts were then zero following the next scan of the partition, (by default this might be 60 minutes although I changed mine to 30) so after weeks of looking at this and getting nowhere, I have concluded that this might just be normal EV chatter and could well just be a red herring, caused by EV writing to the production HCP, then checking for replicaiton to the second HCP, before replication had been completed.

But if anyone knows better and can suggest some new avenue to check, I'd be happy to join in and help diagnosis because I can reproduce this error at will and its been bugging me for weeks.
