Hi Team,

What is the exact process for vss vm backup. still it is following the esxi host and datastore concept for vm backup. then how we can check the datastore space issue.

Can any one assist on this?

    @Siva For Windows VMs that are running, Backup coordinates with Windows Volume Shadow Copy Service (VSS) to take an app-consistent snapshot of the VM.

    By default, Backup takes full VSS backups.
    If Backup can't take an app-consistent snapshot, then it takes a file-consistent snapshot of the underlying storage (because no application writes occur while the VM is stopped).

    More details can be found here - https://learn.microsoft.com/en-us/azure/backup/backup-azure-vms-introduction#backup-process
