Abstract
The retention lock status for a backup file stored in a storage target of a deduplication backup is certified by obtaining the retention lock status and encrypting, in the storage target, the retention lock status information using an encryption key process to create a certified retention lock status. This signs retention lock status by the entity storing the backup file, rather than an application setting the retention lock. The certified retention lock status is provided as a token to a backup software of the deduplication backup system, wherein the retention lock status information is made available for inspection and audit. It is then returned, in response to an audit request, for comparison against a cleartext representation of changes to retention lock status.
