Abstract
An illustrative air-gapped data storage site for storing secure copies at the air-gapped storage site. Using specialized air-gapped media agents installed within the air-gapped storage pool site, the illustrative system, at an unpredictable time, establishes a one-way tunnel from secondary storage site to air-gapped site to receive backup copies of the data stored at primary site. In another embodiment, during disaster recovery, backup copies stored within the air-gapped site are replicated to a non-air gapped site (e.g., secondary storage pools) as “tertiary copies.” Those copies are then restored to the primary site in original application data formats for quick recovery. As restoration of data is complete, the tertiary copies are promoted to “secondary copies” to receive incremental backups.
