I have had my VM backup performance drop off the cliff in the last week, trying to figure out some bits and pieces
One thing I see in the ‘Backup Job Details’ is the many VMs at 90%
What is the actual status at this point?
They seem to be here for a long time, so any thoughts would be appreciated
Thanks
Hi jracjdb2,
At 90% it’s usually reading the final few extents of a VM. You should be able to track exactly what is happening in vsbkp.log on the access node for the VM. I have previously seen VMs get stuck at 90% due to read issues or VDDK deadlocks.
I’d suggest checking the logs and see what events are being reported.
If you want general troubleshooting ideas you can also try a storage vMotion from the source datastore to another and then back to the source. It’s an odd suggestion but this can often resolve read request issues.
If it’s a VDDK deadlock occurring you may want to look at which VDDK is being used and the transport mode but that may need a support incident to investigate properly.
