Digital preservation: 3 copies

The Association of Personal Photo Organizers (APPO) recently shared this radio conversation about digital preservation from St. Louis Public Radio.  The conversation is 30 minutes long and includes input from librarians, archivists and digital media managers; there is an accompanying article that addresses the highlights.  Key takeaways include:

  1. Always have multiple copies, in a variety of formats and on different devices (this helps to guard against different hazards).  I recommend three copies to my clients (e.g., hard copy, external hard drive, cloud storage).
  2. Be prepared to migrate digital files from one format to another in the future; evaluate the situation every 5 years or more often.
  3. Checksums can be run on files to detect corruption and hopefully give you time to address it before it advances too far.
