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. This signs the RL status by the entity storing the backup file, rather than an application setting the retention lock. The certified RL status is provided as a token to backup software of a deduplication backup system, wherein it can be made available for inspection and audit. The data may include opaque data that is data not interpreted by the filesystem. The request for RL status includes the opaque data, which is returned as part of the response, and which can be returned in part as cleartext.
