Abstract
Example apparatus and methods access a Linear Tape File System (LTFS) repository that stores data associated with an external entity (e.g., file system, application). Data is copied from the LTFS repository, selectively converted to a form associated with a cloud repository, and provided to the cloud repository. A mapping between corresponding addresses in the LTFS repository and cloud repository is established. Requests by the external entity for data may be satisfied from either the LTFS repository or the cloud repository until a changeover event is detected and are then satisfied from the cloud repository afterwards. The external entity runs on a different computer than the method. The method is transparent to the external entity, is performed independent of the external entity, and continues under its own control until a selected amount of data is moved from the LTFS repository to the cloud repository.
