The National Library underwent a major overhaul of its digital preservation system, transitioning from DSM to DPS for long-term preservation of its historical materials. A crucial part of this transition was the re-archiving process of 2.2 million hours of digital radio, which included born-digital and digitized radio programs from 1993-2022. Surprisingly, during the re-archiving process, discrepancies were found in 577 out of 2.2 million objects, with errors related to checksum mismatches, corrupt files, and duplicate files. The transition resulted in 2.1 million new MP4 files and 143TB of new playback files. This initiative underscores the National Library’s commitment to preserving digital radio material for future generations.
