Abstract

Example implementations relate to encrypting data objects. In an example, data objects of a file system instance contained by a security domain are encrypted using a Data Encryption Key that is specific to the security domain and is wrapped by a Key Encryption Key shared exclusively within a cluster. A root object of the file system instance is encrypted using a Metadata Encryption Key. A backup of the file system instance is created on a backup node. The Data Encryption Key and the Metadata Encryption Key are sent to the backup node.
