Web developer Ukiah Smith wrote a blog post about which compression format to use when archiving. Obviously the algorithm must be lossless but beyond that he sets some criteria and then evaluates how some of the more common methods line up.
After some brainstorming I have arrived with a set of criteria that I believe will help ensure my data is safe while using compression.
- The compression tool must be opensource.
- The compression format must be open.
- The tool must be popular enough to be supported by the community.
- Ideally there would be multiple implementations.
- The format must be resilient to data loss.
Some formats I am looking at are zip, 7zip, rar, xz, bzip2, tar.
He closes by mentioning error correction. That has become more important than most acknowledge due to the large size of data files, the density of storage, and the propensity for bits to flip.

When I was a young pup of sixteen I remember seeing ads for sale in the back of my dad's Popular Mechanics magazines for the miraculous Pogue carburetor. Of course as a poor kid making minimum wage, struggling to keep the tank filled and a bit mechanically inclined, i was sorely tempted to order a set of plans and try my luck implementing it. Fast forward a couple years and some freshman physics and I realized how foolish I was to entertain the idea.
