Abstract
A self-healing method of recovering files using a cyber recovery vault for deduplication filesystems. Data to be backed up from a production system to a backup system in a datacenter is also copied to a cyber security vault coupled to the data center through an air gapped connection. A copy process makes a point-in-time (PIT) copy of the portion of data to a namespace in the vault, and retention locks the copied portion in the vault. An automated process detects a missing segment error, such as due to a bad index lookup in the data to be backed up. The self-healing process provides the missing segment from the PIT copy in the cyber security vault. For any missing fingerprints the process adds the data in new containers and the references in the index, providing an indirection that allows for just writing a new container with the missing L0 references and updating the index.
