This question was inspired by http://superuser.com/questions/374386/how-to-store-and-preserve-lots-of-data. There have been other similar questions, but none with the same criteria.
This is two questions in one.
- How do you store financial/critical records that should survive anything but a fire and should be available for decades?
- Lets say I want to store family photos/videos and want people do be able to find them in storage 100 years from now and still be able to use them. How would this be done?
- Long term means 30+ years guaranteed. 100+ years average. [If this is not practical, use the closest solution]
- High volume means a couple terabytes.
- Answers can be 'no-compromise/industrial' solutions or practical solutions for the home office/small business user.
- Media will not be active during the timespan. (i.e., if you suggest hard drives, they will not be spinning).
- Further, there is no expectation of needing to read these archives. They are there for emergency or "for future generations" purposes.
- Should not require maintenance (if at all possible).
- CD-R/DVD-Rs have proven to me, even in the short term, to be a terrible medium for backups. They seem to be very fragile and seem to lose their data a very short time even when in pristine condition.
- I can't help but think that storing data on a couple of 1TB hdd's and then expecting them to spin up correctly a decade or two later to be a terrible idea. Am I wrong?
- Industrial tape drives seem like a viable option?
