Abstract: The described embodiments set forth techniques for preserving clone relationships between files at a computing device. In particular, the techniques involve identifying clone relationships between files in conjunction with performing operations on the files where it can be beneficial to preserve the clone relationships.

In this manner, the various benefits afforded by the clone relationships between files can be retained even as the files are propagated to destination storage devices that may or may not support file cloning.

Abstract: Certain embodiments disclosed herein provide attestation for a transient version of an application while reusing the attestation and the cryptographic key on which the attestation is based for the full version of the application should the user obtain the full version of the application prior to the transient version being deleted.

Associating the existing key with the full version of the application enables the full application to automatically take over the attestation previously provided for the application clip, saving time and resources that would otherwise be used for establishing a new attestation for the full version of the application.
