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.
