All,

Ever since we upgraded our Hyper V hosts to Server 2016 we have had nothing but issues with our backups.  We are using Veritas Backup Exec 16.  So when I run a full back up it runs find on all of our VM's except for 1.  I receive the exception V-79-57344-38721 - Failed to mount one or more virtual disk image, and then it fails to back up any data.  When I run an incremental all of my vm's throw the same exception,  V-79-57344-38721 - Failed to mount one or more virtual disk image, and then it fails to back up any data.

Has anyone experienced this or know how to correct it?

Thanks!
