About the Long-term backup Problem.
What kind of data?
- source code;
- photographs;
- music;
- video;
- mail;
- books, papers, etc;
- administrative data (bank statement, invoices, etc.).
Data format
- better if not encumbered by any known patents; ogg, png, etc.;
- popular format: MP3, JPEG, etc.
Space
- need more and more space;
Where to backup?
- On line:
- privacy
- expensive
- Network Attached Storage:
- not long-term
- CD/DVD
- hard to keep backups up to date
- TAPE
- transfer rates
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).
