Restoring Encrypted Data

To restore encrypted data, you must specify the security key that was used to encrypt the data when it was backed up. If you do not specify the correct security key, CA VM:Backup cannot create the request. For a description of how CA VM:Backup encrypts data for a backup, see Using Encryption for Data Security.

You can use the function screens to restore encrypted data. The CA VM:Backup file selection screen displays the ** Encrypted ** descriptor for minidisks and directories that were encrypted during the backup, regardless of whether the data was backed up in CMS, SFS, or physical format. When you select ** Encrypted **, CA VM:Backup asks you to specify the security key used to encrypt the data. If you enter the correct security key, CA VM:Backup displays a second screen; the information and selections displayed on this screen depend on whether the backup was logical or physical.

If you use a restore job template file to restore from an encrypted backup, the associated exception file must specify the security key on the SECURITY parameter of an OPTIONS record. For information, see the OPTIONS record for restore jobs in the Template Programming Interface Guide.
