- Store the converted files along with the original PCX files if you need to retain the lossless quality or metadata. The PCX files can serve as an archival master copy.
- Migrate the files to current digital storage media periodically as older media degrades or becomes obsolete. Hard drives, optical discs, tapes etc. have limited lifespan.
- Back up the archive to multiple locations for redundancy. Use cloud storage, external drives, discs etc. Follow the 3-2-1 backup rule for best practices.
- Document important metadata like descriptions, dates, keywords to aid in search and retrieval. Store this in a separate database with links to the image files.
- Use appropriate file naming conventions, folder structures and cataloging to organize the archive. Group similar images together.
- Limit access to originals, provide derivatives for public access. This helps preserve integrity of valuable archival images.
- Display a small sample set online for public access but limit full downloads. Watermark images if needed.
- Every few years, rerun file conversions, migrate to new media, and audit integrity of backups. Keep the archive up-to-date.
Let me know if you need any other specific recommendations on managing and preserving an archive of PCX images. I’d be happy to provide more details or advice.
