ItвЂ™s also expensive the handling mechanisms are finicky and because data is stored sequentially, random retrieval is quite slow. But tape can stretch and break, as well as be erased by magnetic fields. ItвЂ™s also removable media, so itвЂ™s easy to store and handle in bulk. ItвЂ™s available in very large capacities-a new Sony type can hold up to 185TB. Magnetic tape is still in the discussion for enterprise. Figure 10 years as a best case scenario, but donвЂ™t rely on it.ДЄdvice: If you use SSDs, refresh the data on them every year or two and replace them every 10. The technology is also relatively new, so no one is quite sure how long an SSD will retain data when stored unpowered, but you wonвЂ™t find companies touting them for long-term backup. The cells, which are electron traps, leak over time.

SamsungвЂ™s Portable SSD T1 is super fast-up to 350MBps faster than USB 3.0-but most NAND-based storage is only good for about a decade or so.Д®xternal SSDs are rugged and virtually shock-proof, but the NAND they use wonвЂ™t hold data forever. Write-protect them (see the вЂњMethodologyвЂќ section) before storing them, and rewrite the data every couple of years. You can do everything right with your drive, but drop it on a hard floor as you pull it out of the safety deposit box, and like that, youвЂ™re off to the recovery service.ДЄdvice: If you use hard drives for archiving, use them in pairs or trios-each containing a copy of the same data. A hard drive is also a mechanical device thatвЂ™s vulnerable to shocks.

Consumers can do this with free software called DiskFresh.Д®nvironment is also key: Heat, vibration, humidity, and magnetic fields (strong ones are used to erase hard drives) can dramatically shorten operational or shelf life. It figures a loss of magnetic strength/signal at anywhere from 1 percent per year, to 1 percent per decade.ДЇor non-operational drives, itвЂ™s industry practice to refresh, i.e., rewrite the data every two or three years. That decade or two longevity figure is based on published figures for coercivity and residual magnetism for current GMR (Giant MagnetoResistance) and SMR (Shingled MagnetoResistance) recording techniques, as well as the latest platter coatings. For the long term, hard drives on the shelf are workable, but require periodic maintenance-so they are not ideal. In constant use, mechanical stresses shorten a driveвЂ™s lifespan to three to five years. Fast compared to tape and optical, hard drives are generally reliable for the short term, and if removed from operation and safely stored, may last a decade or two before magnetic properties diminish to the point of producing unrecoverable errors. Portable hard drives are easy to use, faster than optical, but may need their data refreshed every few years.Д«y far the most common backup media employed by consumers is the external hard drive. WeвЂ™ll discuss methodology later, but hereвЂ™s the low-down on the media types available for backup and archival purposes. Securing your data for posterity, i.e., archiving, requires a different approach, where shelved media life and future file compatibility trump the speed and convenience that make backup palatable to the average user.

A lot is written about the importance of backing up data, but the media and methodologies proposed arenвЂ™t generally suitable for archiving.
