Abstract
The retention lock (RL) status for a backup file stored in a storage target is certified by obtaining the RL status and encrypting it using an encryption key process to create a certified RL status. Verification logs are kept by appending the time of certification to a new token that can be audited. Each time a certification is attempted, a log corresponding to the latest attempt and the latest timestamp is added to the end of the verification list. This verification log may be implemented through a verification timestamp is appended to the token, or a verification log that is its own token. The verification log is maintained in a backup system and made available to an auditor for review of the certified RL status of the locked files.
