Abstract
A data management device includes a persistent storage and a processor. The persistent storage includes an object storage that stores segments. The processor generates a collision free hash function based on the segments, generates a hash vector using the collision free hash function, deduplicates a portion of the segments associated with to-be-migrated files using the hash vector, and migrates the to-be-migrated files using the deduplicated portion of the segments to a remote storage.
