Check readiness show no Issue.
The error in vsbkp.log:

Hi @Mostafa Amin 

Thank you for the question.

The error indicates that Commvault requesting the VMware to take a snapshot of the VM, but VMware is declining to perform the snapshot.

This could be because the VMware ESX host is in maintenance mode.

Case history here at Commvault does show some cases where the maintenance mode activity became stuck on the ESX host and this needed to be resolved in VMware before successful backups could be taken.

Please check the status of the ESX host and see if that reveals anything.

Thanks,

Stuart
