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.
Enable file recovery for VMware virtual machines
NetBackup has a feature calledEnable file recovery from VM backup thatallows the restore of individual files from VMware virtual machine backups. How is this any different than using GRT? Can you use GRT on a VM and restore a single file from a snapshot backup?Exchange 2013 GRT backups - how can I speed up the backup?
Hello, we have two mailboxes servers hosted on vmware and 30 databases configured in a DAG between the two servers. currently I have a policy set for a 15 hour window for a full GRT backup during the night (between 17-8), and 7 jobs limit per policy. lately the backup fail to complete in the time frame we have. and this is after we lengthenedit already. other than increasing the job limit, how can I speed the backups? the servers seem to struggle as it is (I think the backups are causing them to lose connection with the witness server- I never had the time to look into it) I consideredticking the 'disable client side deduplication' on the policy, since we are using a netbackup appliance with deduplication enabled. but I was unsure of where it moves the workload.. thanks in advance for the help
