Abstract
Methods, apparatus, and processor-readable storage media for deleting orphan archived files from a storage array using a time-based decision algorithm are provided herein. An example computer-implemented method includes traversing a database of a local storage system to identify a record associated with a stub file, wherein the record is indicative of a time of a client operation, involving the stub file, on a file system of the local storage system; identifying a particular snapshot in a set of available snapshots of the file system; and providing an indication to a cloud storage platform to delete a cloud object corresponding to the stub file in response to determining that the time of the client operation occurred earlier than a snapshot time associated with the particular snapshot in the set.
