Another thing that happened to me once, back in my sysadmin days, is that a drive controller went bad and started writing data onto the wrong hard drive tracks. The backup system was working correctly, and didn't report any errors, but the data was already corrupted before it was backed up. Once I figured out what was going on, and replaced the faulty hardware, I then had to restore data, check if it was good, restore the previous day's backup, etc. Two weeks back, I finally found reliable data. Then, all of the transactions done in that two-week period had to be re-entered, frequently meaning that we had to have customers send us orders again, while making sure that old orders didn't get double-shipped and any new orders DID get shipped. It took a month, with most of the company's employees putting in overtime, before we were completely up-to-date.

We need to at least power up the keyfobs every year or so, to allow the hardware to 'refresh' the flash. It does erode over time, and the odds are high that if you just toss it in the safe deposit box that it may not be readable in 5 years or even less. ... Bummer. Back in the 'dark days' Byte magazine published a 'bar code' that could be used with a hand 'light pen' type scanner, to allow printing full page bar code data on a sheet of paper, and using the pen scanner to restore the data. ... They did use a KISS method, that made it interesting at the time. These days with good cheap printers and scanners, should be able to do something like that with higher density and reliability.
