Resolution
These messages are seen during the backup when the VHDX ( Hyper V VM disk ) is mounted for catalog generation. These messages will be seen on Backup Exec Server if backing up to a disk storage or on the Hyper V server if backing up to a Tape/OST or Cloud Storage.
These errors can be ignored if seen during the time of the GRT Backup. These errors should not cause loss of backup performance.
