Which recovery mode involves rolling back a system to a previous recovery point instead of finding the cause of a fault?

the answer is wrong
Backward recovery
• Involves rolling back or restoring a system to a previous recovery point. Instead of finding the cause of a fault, it aborts changes that have produced a fault and resorts to reversing previous operation or state of a process.
− For example, the memory state, settings state, and power state (on, off, or suspended) of a virtual machine (VM) is saved at a specific recovery point so that the VM can be restored to its previous state if anything goes wrong.
