Backing up your data simply means making a copy of it. separate from the original version on your computer's hard disk. You can back up the entire disk, programs and all, or you can back up up your data files. If your original data is lost, you can restore the backup copy, then resume your work with no more than a minor inconvenience. Here are some tips to help you start a regular backup routine.

The most popular backup medium is the floppy disk, but you may need dozens of them to back up all your data files. A tape drive, removable hard disk, CD-RW, or DVD-RW drive may be a perfect choice if the medium provides enough storage space to back up your entire disk. When choosing your backup medium, the first rule is to make sure it can store everything you need. 

It also should enable you to re- store backed-up data and programs with little effort. You can find medium-capacity tape drives and Zip drives for as little as $100 to $300. Prices increase with speed and capacity. Large-capacity disk cartridges, such as Iomega's Peerless system, start at around $350 for the drive; 10 GB Peerless disks cost about $150; and the 20 GB version costs about $200.

Remote backup services are a growing trend. For a fee, such a service can connect to your computer remotely (via an Internet or dial-up connection) and back up your data to their servers. You can restore data remotely from such a system.

For backing up your entire hard disk to a high capacity device, use the file-transfer software that came with the de- vice. Your operating system also may have a built-in backup utility that works with several devices. The critical issue when choosing backup software is that it should enable you to organize your backups, perform partial backups, and restore selected files when needed.

Set a Schedule and Stick to. It Your first backup should be a full backup-everything on your hard disk-and it should be repeated once a week. Beyond that, you can do a series of partial backups-either incremental (files that have changed since the last partial backup) or differential (files that have changed since the last full backup).

• What is the most secure way to store data?

Be sure to keep your disks or tapes in a safe place. Experts suggest keeping them some- where away from the computer. If your computer is damaged or stolen, your backups will not suffer the same fate. Some organizations routinely ship their media to a distant location, such as a home office or a commercial warehouse, or store them in weather and fire proof vaults. Home users may want to keep their backups in a fireproof box. 

Companies of- ten keep three or more full sets of backups, all at different sites. Such prudence may seem extreme, but where crucial records are at stake, backups of files are vital to the welfare of a business.

Looking Back, Moving ForwaofficeIf there is any quality of a new technology that limits its adoption into the growing world of the PC, it's backwards compatibility. As the name suggests, backwards compatibility means that the technologies of tomorrow work with the technologies of today. (Similarly, forward compatibility means that today's technologies will work with the technologies of tomorrow.) Backwards compatibility (BC) is the point at which technological innovation meets economics. 

More simply: people will buy new stuff when they don't have to throw out all of their old stuff to use the new. Sometimes, even partial BC isn't enough. VCRs that sup- ported the advanced SVHS video format could play traditional VHS tapes, but the higher-quality SVHS tapes they recorded couldn't be played on VHS VCRs. This meant consumers couldn't share SVHS home videos with grandparents and cousins unless the whole family bought SVHS machines. It never happened.

Having learned this and many similar lessons, the consortia that defined the various formats for recordable compact discs kept BC at the forefront of their work. The result? An audio CD-R burned in the world's fastest drive will still chug out tunes on Sony's original Discman from 1984. The importance of backwards compatibility was briefly lost, however, when many of the same companies worked together to develop the recordable DVD. 

In fairness, the issue wasn't just s that manufacturers chose against BC. The technology didn't t yet exist to make affordable, recordable DVDs that would work in the established base of DVD-ROM drives and home players. But, as late as 2003, many manufacturers continued to assume that purchasers of still-expensive DVD recorders wouldn't care if they could share home videos with grandparents and cousins. Sound familiar?

With no fewer than five major contenders for the "recordable DVD format crown," the matter seemed unlikely to resolve itself quickly. Then, home player makers realized they could provide compatibility with four of the five for- mats at no additional cost. Indeed, the price of home units has plummeted. This is supply and demand: Make your product usable by the most people, and you'll sell so many that you can lower the price. DVD recorder manufacturers have followed suit. Virtually all new DVD recorders can write discs in any of the four formats.

This might have been the end of the race were it not for two factors. First, recordable DVD discs are not just for video. They're used for PC backups, moving files, and so on. So they're subject to the same requirements of any other PC storage media. Briefly, these are ever-greater capacity, greater speed, lower cost, and BC. The second factor is that commercially released video DVDs have a higher storage capacity than first-generation recordable. 

Consumers couldn't easily back up the DVD movies they bought, and smaller video production houses couldn't produce DVDs with the same broad features consumers expect in commercial products. Why do commercial discs have higher capacity? They implement two layers of recording material. The laser reads the second, fully reflective layer by shining right through the first, semi reflective /semitransparent layer. Dual-layer DVDs are economical-one disc costs less than two-and are convenient for users (no discs to turn over). Naturally, home players have supported dual layers for years.

Because the dual-layer idea already existed, it gave the DVD consortia a target for high-capacity recordable DVDs: backwards compatibility. This proved difficult. Commercially released DVD discs are made by completely different means than are recordable. The former are actually pressed, whereas most of the latter rely on phase changes in a crystalline layer. 

These simulate a pressed DVD's pits and lands. So any BC dual-layer system had to function like existing recordable discs and like commercial discs. The developers of the generally superior DVD+RW format were first to succeed, with the first drives available in 2004. Their achievement was both a technical and a political success; the motion-picture industry has attempted to stop the development of DVD technology because of fears that widespread copying of DVD movies will destroy their business model.

There comes a time in any technological chain, however, where backwards compatibility has too many drawbacks to make it cost-effective or even reasonable. This happened when the market embraced DVDs over CDs, so we could have full-length, high-quality digital movies on a single disc. Blu-Ray laser drives will likely be a similar successful break from BC. Announced in late 2003, Blu-Ray optical drives use a blue laser instead of the traditional red DVD laser or infrared CD laser. Blue lasers produce light at shorter wavelength than the others, so pits and lands can pack more densely. 

Blu-Ray provides 23 GB of storage on a 120 mm disc. That translates into 13 hours of standard video (conveniently, just over two hours of the forthcoming HDTV video). Planned improvements will take the capacity up to 100 GB, positioning these drives to replace the VCR and disk-based personal video recorders. Since a different laser type is required, Blu-Ray discs won't be playable in existing DVD players. However, DVDs and CDs of all current types should play in Blu-Ray drives with no trouble.
