HyperBack task behavior when backing up multiple virtual machines

Details

When creating a HyperBack task with Create backup image file of multiple virtual machines enabled, the task behaves as follows:

1) If an error occurs on any virtual machine, the entire task fails for all configured guests. For example, if snapshot creation fails for one VM, the task stops and fails, even if other VMs could have completed successfully.

2) If some virtual machines are missing because they were removed from the inventory, those VMs are skipped and the task continues for the remaining guests. If the task completes successfully, it is marked as successful.
