Precious emotion evoked by an old picture is a joy, yet the idea of losing that snapshot forever motivates one to consider best practices regarding document storage. What are best practices regarding saving precious documents such as images, audio, and videos?
Recommended Best Practice
Practically speaking, a copy stored on duplicate DVD's is recommended, and for extra precious documents, print out a copy as well. You want two DVD's - a copy, and a backup.

Have a family member or friend that lives in another city keep the backup.

The method of storage is a compromise between convenience and cost. Self replicating storage seems most reliable. In other words, storage which continuously builds copies of itself, e.g. human beings. Albeit, humans are known to struggle with understanding the meaning of their life.
