Abstract:
A method for handling snapshots together with migrated files in a hierarchical storage management may be provided. The method comprises managing files using a first-tier storage and a second-tier storage. The files are organized in a managed file system—e.g., a hierarchically managed file system—in the first-tier storage. The method comprises further creating a snapshot of a portion of the files of the first-tier storage, thereby creating a hidden directory in the file system, deleting a migrated file, and moving the stub file relating to the file to be deleted in the first-tier storage to the hidden directory.
