Issue Description:
The backup copy of VMware VM backup in Commvault reported failure. The backup jobs failed with the following error:
Error Code: [14:21]
Description: UpdateIndex index processing failed forResolution:
Login to the proxy VM and review the updateindex.log and search for the string 'FATAL ERROR'
UPDATEINDEX FATAL ERROR: extent size change detected for vm.
When the VM extent size changes, Commvault incremental backup fails to run. The way to fix the issue is to run a FULL backup and then attempt an incremental backup.
