I am running 7.1.0.3 to backup up my virtual machines. When the policy executes, a majority of systems start and finish successfully, however, I have a few others that are having issues when it comes to creating the snapshot. Instead of a single snapshot for a machine, Vcenter starts trying to create like 5+ snapshots.
The jobs fail in NBU, while the snapshots just sit there.
As a start, ensure that bpfis log folder exists on the Backup Host.
This will give us insight into snapshot attempt from NBU point of view.
I do have the bpfis log folder created
Please post the bpfis log for our review
Thanks
do I have to scrub any data from the log before posting?
No - best to see it all - add it as an attachment
I have attached the bpfis log
Without looking into, I would suggest one idea:

Ok - looked at the logs (all 8MB of it!) and it looses connection with vCenter (times out) whilst waiting for the snapshot.
As it has lost connection it is not able to delete an old one as it does not know it exists and retries 9 times before giving up and failing (hence the 9 snapshots)
The issue is likely to be with the client experiencing the problem - maybe VMTools is not up to date, maybe it has Apps installed such as SQL or Exchange so its tools.conf need editing to prevent app quiesce
If the others work OK then look into what is wrong with that client - maybe its own VSS components - check its System and Application event logs
these netbackup created snpshots shoud go in next backup run, if you are using default "Remove NBU" snapshot option.
If a virtual machine snapshot exists that a NetBackup backup previously created, NetBackup
removes the old snapshot, creates an updated snapshot, and proceeds with the virtual machine
backup.
OK, so a little update.
VMtools are up to date and the systems with the issue are not Exchange or SQL servers.
In testing it appears NBU is timing out and requesting another snapshot. I have increase the timeout to 900 seconds and it is still not enough. If I look in vcenter, the snapshot takes 22 minutes to create. Therefore, when the timeout is reached, NBU requests another and another and another...hence the multiple snapshots. However, this does not explain why the snapshot creation takes 22 minutes. If I manually request a quiesced snapshot from vcenter, the task is complete in under a minute. This is how a majority of my VMs function using NBU for vmware and those backups run and everything is great. It is only a handful of random systems that for whatever reason take an excessive amount of time to create the snapshot, but there is no telling why.
I feel a 30 minute timeout only masks the real issue.
