Abstract
A data management device includes a persistent storage and a processor. The persistent storage includes meta-data of data stored in a long term retention (LTR) storage. The processor obtains a file storage request for a file and deduplicates the file against segments stored in the LTR storage while performing garbage collection on the LTR storage. Performing garbage collection includes deleting segments of the data stored in the LTR storage using the meta-data. The meta-data is not stored in the LTR storage.
