Validation - an operation that checks the possibility of data recovery from a backup.

Validation of a virtual machine backup calculates a checksum for every data block saved in the backup. This procedure is resource-intensive.

While successful validation means a high probability of successful recovery, it does not check all factors that influence the recovery process. If you back up the operating system, only a test recovery to new/existing virtual machine or running virtual machine from the backup can guarantee successful recovery in the future.
