If a virtual machine is migrated (for example, through Storage vMotion) while a backup or restore job is in progress, it can cause a job to fail or it can create orphaned virtual disks on the datastores. To temporarily disable migration, the virtual machines can be locked before a job starts and unlocked when the job is completed.
By default, the locking mechanism is disabled and it is not used during backups and restores.
To enable virtual machine locking
1 Open the vmware.cfg file in any text editor. You can find this file in <NetVault Backup home>\config on
Windows and <NetVault Backup home>/config on Linux.
2 In the [Custom:GetMigrationLock] section, set the Value option to True:
Value = True
3 Save the file.
