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.

Abstract: In an example, a system includes network nodes implementing an object store. The system may determine reference count updates for objects stored on the object store, and delay persisting the reference count updates to a persistent storage. The system may cancel reference count updates that increments and decrement between the determined reference count update and another reference count update received during the delay in persisting the reference count update to the persistent storage to minimize writing to the object record.

Abstract: In an example, a system may modify an object stored in an object store for storing objects to include augmented metadata. The system may encode a signature of the modified object such that the signature is identical to a signature of the object prior to being modified to include the augmented metadata.
