Zusammenfassung:	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 backup of the file system instance is created on a backup node. The backup includes at least some of the encrypted data objects. The DEK is sent to the backup node. The backup node cannot decrypt the backup unless the backup node is a member of the cluster and has access to the KEK to unwrap the DEK.
