have DVDs I used for backup six or seven years ago, if I didn't have
later backups, I'ld be in trouble because I get read errors on most of
them. I've faced similar issues with tape, hard drives and the like.
This is one of my favorite technical questions!If you have __ANY__ type of data and you want to be guaranteed that you will be able to machine-read it in 20 years, what media will you use to store it?I've been using and building computers since the mid 1970's. My first programs were stored on paper tape or DECtape, both long gone. 8" floppies are history, as are 5.25" floppies. Even the 1.44 MByte floppies are getting hard to find. Store it on an MFM drive from the original IBM PC? Good luck finding a computer to read them on. PATA/IDE drives are now obsolete, although most motherboards still have the connections, but for how long? CDs and DVDs are popular now, but even if the media survives, will computers in 20 years still have the drives? Probably not.IMHO, there is __ONLY ONE__ media that is guaranteed to be machine-readable in 20 years: paper.If a human being can read the data, a computer will be able to also. Any other media will have a technical life of about 20 years max. Even if the media survives, the hardware to read it will be obsolete and very rare.So store those tax records in file folders and keep them in a cool, dark, dry place.
Sounds like you're an advocate of Optar Casey. |
