NetBackup 8.3 - Active Directory GRT is Broken
Hi All, Just found another bug in NetBackup 8.3 related to AD GRT jobs. Apparently the image duplication phase where the real mapping should happen between the Backup Image and AD is failing miserably. I noticed couple of things while I was observing the entire process. For the moment I'm not sure if the issue is with the NBU client only but I will make few more tests including a client downgrade to rule out possibilities. 1. When the initial "System State" backup is being taken from a Domain Controller, the jobs sometimes fail with the following message: error encountered while attempting to get additional files for system state:\ Obviously there is also an indication that initial GRT information assesment was unsuccessful. Unfortunately this behavior doesn't seem to be very consistent over the jobs so the failure seems to appear randomly. This have happened on 4 different DC's some of which are RODC. Once I managed to get a healthy image from the DC's I moved on to the duplication part. 2. During the duplication phase I noticed that the "nblbc.exe" binary is constantly consuming an entire CPU core for a while but it is not yet clear what happens in the background. The binary runs like that for about 20-30 minutes non-stop then it terminates with the following message within the "ncflbc" log folder: 0,51216,158,351,52,1596142489535,6192,1152,0:,53:SpsRestoreCurrentVer:False (../ResourceChild.cpp:719),28:ResourceChildBEDS::_attach(),1 0,51216,159,351,1,1596144159553,6192,1152,0:,89:write() failed, wrote 0 of 276, error 232 (Unknown error) (../TransporterConsole.cpp:219),27:TransporterConsole::write(),1 0,51216,159,351,2,1596144159568,6192,1152,0:,256: An Exception of type [FileWriteException] has occured at: Module: ../TransporterConsole.cpp, Function: TransporterConsole::write(), Line: 225 File:*Console* OS Error: 22 (The device does not recognize the command. ) (../TransporterConsole.cpp:225),27:TransporterConsole::write(),1 0,51216,311,351,1,1596144159568,6192,1152,0:,69:exception in m_transport->write() (../BRMObserverDepreciated.cpp:407),29:BRMObserverDepreciated::write,1 0,51216,159,351,3,1596144159568,6192,1152,0:,50:Terminate Signal called .

When I try to view the content of the images throuhg "BAR" client, I have partial success. Although I'm able to open the "System State" and "Active Directory" folders any subsequent tries further through the OU's are making the client to get stuck with "Communicating with server" messages. Those folders that I managed to open were indicated throuh respective restore jobs in NBU console but no further jobs have been generated. Once the timeout has been reached approximately 5 minutes later. another "ERROR: file read failed" message appeared on the screen. I haven't yet turned on debugging for "bpbkar" or "ncflbc" logs but I will collect those in case NBU client 8.2 wouldn't solve these issues. Also I noticed that it doesn't matter between which type of storage pools I would engage the deduplication. I tried Adv. Disk to Adv. Disk and also Adv. Disk to MSDP but the result is all the same. As it seems the process is stuck somewhere on the client side. My GRT AD implementation used to work perfectly with NBU 8.2 and except for the recent upgrade to NBU 8.3 nothing else has changed in the environment. Any suggestions on the debug logs or other aspects are highly welcomed. Cheers.1.6KViews0likes3Commentsbackup failed Active Directory
hi everybody, im trying the creat a policy of backup active directory, i need backup the objects like "DC=internal", but i when execute the backup in the client, show me the next log, "Backup by "account" on client "name_of_server_client":the specified policy does not exist in the configuration database." the policy have the next specificacions; is ms-windows the backup selections is System State:\ i hope your help. the master server is a version 8.0, linux.808Views0likes2CommentsAD GRT - vmware snapshot
Hi, this must be a subject discussed countless of times- regardless I havn't quite found the answers I was looking for. I am trying to figure out if I can and should backup Active Directory using vmware snapshots, and if it is possible to use GRT with snapshots. this article firmly states against it: http://techgenix.com/dont-snapshot-domain-controllers-96/ however this old thread I found: https://vox.veritas.com/t5/Backup-Exec/Backing-up-AD-in-a-VMWare-VM-Using-GRT-Causes-Job-Warnings-Safe/td-p/529685 suggests it's fine to use snapshots to backup AD. moreover it suggest that with"active directory agent license installed on the media server" I will be able to use GRT. so I am left with two main questions: 1) can and should I backup AD with vmware snapshots? 2) what is this "active directory agent license installed on the media server"- does RahulG mean a regular netbackup client installed on the DC or is it an actual agent on the media server capable of expanding the snapshot to restore single users or etc.? thanks in advanced for the helpSolved3.8KViews0likes7CommentsNBAC of several Linuz NetBackup Domains to Active Directory
Hi, I have several NetBackup 7.6 Domains (live, Test, etc) that are currently running Linux. We wish to authenticate users on each NetBackup Domain to AD to utilise NBAC. I am thinking installing an Authetication Broker any thoughts/advice? I have found some items referring to an articleTECH199281 however that no longer seems to be available,1.6KViews0likes4Comments
