Abstract
An apparatus in one embodiment comprises a storage system having at least first and second storage tiers each comprising a plurality of storage devices. The first storage tier implements a file system having a user visible name space and a corresponding hidden data store. The second storage tier implements a cloud-based object store. The storage system is configured to controllably relocate files from the hidden data store of the file system of the first storage tier to the cloud-based object store of the second storage tier. In conjunction with the relocation of a given one of the files, the given file is replaced in the hidden data store with a corresponding stub providing user access via the user visible name space to an object comprising the given file in the cloud-based object store of the second storage tier. The controllable relocation is illustratively performed in accordance with one or more configured policies.
