most reliable backup media?

[BigCletus]

This is not really dedicated to just linux but, what is the best type of media to backup data onto? I don't trust CD-Rs over a peroid of time. Would tape backup be better? I have some files that I cannot afford to lose. Thanks.

The most reliable media is pen and paper :)

What I really think you mean is shelf life. Is this saving data from a one time event or standard backups? How long do you need to save the data for?

In my line of work we need to store data for historical purposes on the order of 10 years or so. And since most modern data storage fits its more of whats the best method at the present time. Of course technology as fast as its changing might mean that what was saved 10 years ago is useless today with out any way of retrieving it.

I think the key is if you take proper care and follow the manufactures storage requirements then it should last a min of its shelf life. CD-Rs once burned are supposed to be reliable for 60 years. Probably not.

I use DLT and AIT tape drives for most data storage. They have a life based on tape head passage of 500,000 times. Of course these units are not cheap compared to a CD-R drive but then they are buildt better too.

Good luck

Well, I know here at work they store all patient files on optical platters. Tape drives are only used for shorter duration backups, weekly, etc...

For stuff i could not afford to lose, I'd make TWO CD backups on quality CD-R media. Verify the data on both, then store one away & never use. The other can be used when you need to pull the data for usage.
