NetBackup 8.3 - Exchange Policy Bugs

Hi All,

Just upgraded my NetBackup environment from 8.2 to 8.3 and I noticed the following bugs with Exchange policies.

1. When I try to create a new policy I simply can't finish the procedure because of the following error:

Please select a valid snapshot method using 'Snapshot Client Options'.

Now when I hit the corresponding "Options" button on the policy screen, nothing happens and I'm not able to see the usual screen where the VSS method is chosen by default with it's corresponding parameters. Everytime I hit the "Options" button literally nothing happens and the only way to save the policy is by unticking the "Perform snapshot backups" checkbox which at least will let you hit the "OK" button at the bottom.

When I reopen the same policy, the "Perform snapshot backups" checkbox is once again ticked but still there is no way to modify anything within the "Options" section.

 

2. When I run the newly created policy, I receive the following error message:

This type of backup is not supported on this version of Exchange

the client type is incorrect in the configuration database  (72)

By my best knowledge both Windows Server 2019 and Exchange 2019 CU6 are fully supported and my policy is set just as per the expected rules according to the NBU documentation. So all in all right now it is impossible to backup Exchange with the new NBU 8.3 version.

Any suggestions you may have are highly welcome.

For the record I don't have active support contract with Veritas therefore I can't open a support ticket with the vendor.

    One more thing...

    I tried creating the policy through another NBU Console that was installed on one of my media servers. Unfortunately that didn't help at all. I'll try to create / modify the policy via CLI and see if that would help.

      Just another update:

      I tried some modifications throuhg CLI via the "bpplinfo" command but nothing really helped. Although I can modify any other parameter of the policy via CLI, it just doesn't want to cooperate with the "snapshot" parameters.

      I also tried making the modifications manually through the policy's "info" file under the "VERITAS\NetBackup\db\class\" folder by adding the...

      SNAPSHOT_METHOD VSS
      SNAPSHOT_METHOD_ARGS prov_type=0,max_snapshots=1,snap_attr=0,method=VSS

      ... parameters to it but that also didn't make any difference. In fact the parameters were immediately removed by NBU in the background.

      I looked also at some other policy types against the snapshot option and unfortunately the result is all the same.

      Apparently this seems to be a huge bug in NBU 8.3 so be carefull with your upgrades for the time being. If anyone from Veritas is monitoring this topic please take a look at this issue ASAP as it may affect a lot of customers. Also if you have any suggestions then please let me know, so that I can put some additional tests in my LAB.
