Restoring a VM from backup may take significant time, as it is necessary to retrieve its data from a backup and reconstruct an original machine. However, in some cases, you do not have much time to wait until this process is complete. For example, the original VM got damaged, and you do not have a replica of it or the replica does not contain necessary data. The other case is a testing of software updates: you might want to see how they work before applying them to the production VM, and you want to do this quickly. So here, the Instant VM Recovery (Flash VM Boot) can help.
