sorry for the late reply. Been trying a few tests and wanted to report my findings.. Which makes me scratch my head even more.
So we do have two NetBackup environments. One that I have been talking about which is our Windows netbackup 9.1.0.1 that goes to tape (quantum i500 LTO6 tapes).
Our other environment is redhat linux and is netbackup 9.1.0.1 as well and it had a overland NEOXL80 LTO7 tape libraries connected to it.
Both environments are connected to the same "virtual Machine Server" - vmware. Each netbackup environment vmware policies query on the vmware networks to select the various vms for backing up.
So as you know I said we have this particular linux vm that contains a 5TB vmdk and it is taking 24 hours to back it up and its stating that its backing up just over 5TB which you guys stated is expected (all the blocks). I tend to agree with that logic.
But a co worker pointed out to me that we have a similar VM that is also linux VM with a 5TB vmdk as well but is getting backed up on our Linux red hat Netbackup 9.1.0.1 to the LT07 library. The full backup is not backing up all the blocks. its telling me that it only backed up 54 GB for the FULL which is the actual amount of data being used.
So I decided to adjust the vmware policy query that is on the linux netbackup environment to capture the VM that I originally opened this thread about which normally gets backed up in our netbackup windows environment. And the full job that ran this weekend didnt back up the entire 5TB and instead only backed up the amount of data that is in use.
So now Im really confused.. The only difference is that I can see between the 2 environments (windows & linux netbackups) is that the linux netbackup environment vmware policy has multiplexing set to 4 and doesnt have multiplexing Enabled on the storage unit. The windows netbackup environment has multiplexing on the vmware policy set to 1 and then on the storage unit it has multiplexing enabled with the "maximum streams per drive" set to 32. The other difference is within the vmware policy under the vmware tab "advance" options windows has the "snapshot creation interval = 10 and the netbackup linux environment has it = 120
Thanks

So I guess my main question is why is one netbackup environment backing up all the blocks on a full level vm vmdk when the other one isnt. How do I solve why one environment is making that decision and the other isnt.
sorry for the multiple replies.. meant to add this all to one.
If I was to increase verbose logging is there a particular log that I can view to see what is going on with regard to vmware backups etc..
