Digital archiving

About the Long-term backup Problem.

What kind of data?

  • source code;
  • photographs;
  • music;
  • video;
  • mail;
  • books, papers, etc;
  • administrative data (bank statement, invoices, etc.).

Data format

  • better if not encumbered by any known patents; ogg, png, etc.;
  • popular format: MP3, JPEG, etc.

Space

  • need more and more space;

Where to backup?

The case of pictures

My solution

  • NAS:
    • all photographs;
    • real-time backup.
  • print as much as possible on quality material;
  • CD/DVD
    • regular backup, but a little more spaced in time (need to waste a lot of time in order to have up to date backups).

You can distribute your photographs (numeric and printed) in your family.
