摘要： A system and method for backing up critical data of edge devices includes originator, surrogate, and target edge devices as well as a vault-broker server. The critical data, encrypted, is transmitted to and stored by a surrogate. The association of originator and surrogate is managed by the vault-broker server. Encryption protects the data from recovery by unauthorized parties while allowing surrogate edge devices to determine if recovery attempts are made by authorized parties.
