Minimum Preservation Tool
The MPT was designed to make use of existing network storage and compute resources available at most institutions. It is intended to provide greater protection to digital content than a standard network storage offering. The key differences between an MPT solution and standard network storage are replication of content across two or more storage “nodes” and regular fixity checking (checksum validation) of all files on all nodes to help ensure content remains authentic and unchanged.
