An incremental backup of virtual machine 'vmname' was requested, but the virtual machine lacks an existing recovery snapshot. A full backup will be taken to prevent data loss.

Explanation

Removal of the recovery snapshot of a virtual machine does not reset the last successful backup time maintained internally. The lack of a reset creates an inconsistency between the backup time and the hard disk configuration of the virtual machine. A full backup fixes the ambiguity and prevent data loss.

System action

An inconsistency in the virtual machine configuration was detected.

User response

Avoid deleting the recovery snapshot between back up operations.
