Introduction
There is an irony about digital photos: They actually can last without degrading forever (even improve by better imaging software) and yet they are very volatile, many bits on some storage device. To keep you images you need to be able to:
- Find them (backup organization)
- Read them physically (storage integrity on a technical level)
- Read them logically (file formats, data correctness, ...)
- Process them (All the issues of software and output devices)
Some general rules
- Never feel over confident: all fails, hardware and software
- Be prepared for the volume of data
- Store all images and data on at least two different physical storage devices at any time. Better think of 3 to more copies.
- Make backup a habit and not an afterthought
This article tries to cover the big picture to lay the groundwork for more detailed discussions in the future. It is mainly an outline of things to come.
