The Storage Networking Industry Association has released the 100 Year Archive Requirements Survey. Access requires registration.
Here's an excerpt from the "Survey Highlights":
- 80% of respondents declared they have information they must keep over 50 years and 68% of respondents said they must keep it over 100 years. . . .
- Long-term generally means greater than 10 to 15 years—the period beyond which multiple migrations take place and information is at risk. . .
- Database information (structured data) was considered to be most at risk of loss. . .
- Over 40% of respondents are keeping e-Mail records over 10 years. . . .
- Physical migration is a big problem. Only 30% declared they were doing it correctly at 3-5 year intervals. . . .
- 60% of respondents say they are ‘highly dissatisfied’ that they will be able to read their retained information in 50 years. . .
- Help is needed—current practices are too manual, too prone to error, too costly and lack adequate coordination across the organization. . . .
