Validation is an operation that checks the possibility of data recovery from a backup.
Validation of a file backup imitates recovery of all files from the backup to a dummy destination. Validation of a disk or volume backup calculates a checksum for every data block saved in the backup. Both procedures are resource-intensive.
Validation of an archive will validate all the archive's backups. A vault (or a location) validation will validate all archives stored in this vault (location).
While successful validation means 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 in bootable environment to a spare hard drive can guarantee success of the recovery. At least ensure that the backup can be successfully validated using the bootable media.
Different ways to create a validation task
To create a validation task, perform the following steps.
General
Task name
[Optional] Enter a unique name for the validation task. A conscious name lets you quickly identify the task among the others.
[Optional] The validation task will run on behalf of the user who is creating the task. You can change the task credentials if necessary. To access this option, select the Advanced view check box.
What to validate
Validate
Choose an object to validate:
Archive - in that case, you need to specify the archive.
Backup - specify the archive first, and then select the desired backup in this archive.
Vault - select a vault (or other location), which archives to validate.
[Optional] Provide credentials for accessing the source if the task account does not have enough privileges to access it. To access this option, select the check box for Advanced view.
When to validate
Specify when and how often to perform validation.
After you configure all the required settings, click OK to create the validation task.
