Good Day Geeks !
there are two systems that are giving issues while backing up their shadow copy components.
Below is the error:
Volume resolution error for (System State:\System Files\System Files)
We have tried downgrading them as they were running on 7.6.0.1
OS is 2k8 R2
Tried taking backup without using snapshot ,tried VSP but none worked.
Please suggest if we need to check on something.
PS: Also have tried ignoring backups of unresolved drives.
Thanks,
Pranav B

Hi,
Increase the logging to maximum and fire the backup. Check the bpbkar log . Check whether nbu is unable to resolve any path

Not sure if it's relevant to 2008R2, but maybe here?

we did apply this hot fix on one of our systems giving same error but result is same.
We still struggling to get it working.

VSP was discontinued in NBU 7.0 already.
Is the Windows Client a member of a cluster?
What is in Backup Selection for this client?
Have you checked VSS status?
vssadmin list writers
vssadmin list providers
Have you tried to use Windows Backup on the client to backup system state to local drive?
Please show us all text in Activity Monitor Details tab and ensure these log folders exist on the client:
bpfis
bpbkar
Copy logs to .txt files (e.g. bpfis.txt) and upload as File attachments.

Where do the drives reside?
If they are SAN drives located on Hitachi or similar SAN the client may have VSS writers provided by the SAN
You can check to see if anything other than the default VSS writers are installed using:
vssadmin list providers
If so then from the \netbackup\bin\ directory run:
w2koption -backup -snapshotprovidertype 1
This forces the system to use the Windows VSS writers - usually backups get a 156 error but not always.
It can also be a floppy drive mapped to a VMware server or a recovery partition that doesn't have a drive letter assigned
See what the bpfis and bpbkar logs show - you may need to ramp the logging on the client right up

Sory to reply late on this but found issue with unknown entry in the registry.
There was a path of E drive which shadow copy was trying to backup up but in real it doesn't exist ,so i had to exclude unresolved path for E drive and it is backing up fine.
I found the track of this path in bpbkar logs.

You will agree that Pangal provided you with the solution:
Increase the logging to maximum and fire the backup. Check the bpbkar log . Check whether nbu is unable to resolve any path
Please clear the solution for your own post and mark Pangal's post as solution.
Thanks.
