Validating backup archives
The validation procedure checks whether you will be able to recover data from a particular backup,

an incremental backup, the program validates the initial full backup, the selected incremental
backup, and the whole chain (if any) of backups to the selected incremental backup. If the chain
contains one or more differential backups, the program validates (in addition to the initial full
backup and the selected incremental backup) only the most recent differential backup in the
chain and all subsequent incremental backups (if any) between the differential backup and the
selected incremental backup.

chain and all subsequent incremental backups (if any) between the differential backup and the
selected incremental backup.
This information can be helpful, for example, when you find out that a backup archive comprising a
full backup and a chain of incremental ones is corrupted. To troubleshoot the archive, do as follows.
First of all validate the full backup. If it is damaged, all the archive will be useless. When it is not
damaged, proceed to validating incremental backups starting from the oldest, until you find the
culprit. All incremental backups made after the corrupted one will be unusable, but you will be able
to recover the data at least from the previous backups.

You can perform such validations using the Validate Wizard.
1. To validate an archive, click Recovery on the sidebar.
2. Select the archive to validate and click Validate on the toolbar. If the selected archive is
password-protected, Acronis True Image Home will ask for the password in a dialog box.
