Important considerations not addressed in the article
- Ensuring that working copies of data are not corrupted or modified. If working copies are not read only there is a risk that they will be modified by software that accesses them.
- Ensuring that copies are accurate digital copies of the original using data verification techniques such as checksums. Otherwise a single mistake copying the data from one medium to another means the data will be lost and further efforts will only copy damaged data
- Appropriate cataloguing so that data is easily accessed
I've run into these problems preserving family photos. I have photos dating back to the 1990s but most of my collection starts around 2000. To the best of my knowledge I have not lost a single digital photo yet, but I have been surprised by programs modifying tags etc. when I recently started recording and comparing checksums between copies of my photos.
I intend for my photos to outlive me at the very least.
