 Loose Wire -- Just To Be on The Safe Side

By Jeremy Wagstaff
from the 30 May 2002 edition of the Far Eastern Economic Review, (c) 2003, Dow Jones & Company, Inc.

A few weeks ago I wrote about how to back up your files in the case of disaster, theft, stupidity or a combination of all three. But as several readers pointed out, nearly all the methods I suggested have flaws: Backing up to another drive is no good if you don't take the drive with you -- assuming your computer is eaten by Godzilla or your mother sells it in a garage sale while you're at the mall -- or if the drive remains connected and gets eaten by the same virus that destroyed your original data.

 
On-line drives, where you upload all your documents to a Web site, are fine but a bit slow, and you can never be 100% certain the on-line-drive company won't go bust, or that someone won't hack into your data and learn all your darkest secrets. Backing up to a CD-ROM is cheap, but they have a habit of corrupting data without telling you.
 
When my laptop was stolen a year ago, I was fairly sure I hadn't lost much data until I found my back-up to CD-ROM was a melange of zeroes and ones. Not my idea of a safe back-up.
 
My answer to all these gripes is: All true, but maybe we're addressing the wrong problem. Unless you're a real data dude, chances are your most important data -- ignoring all those thousands of company letters, ageing CVs, letters to old flames and what-have-you that are clogging your hard drive -- could be limited to about 100 megabytes. (Doesn't sound like much? Remember that 10 years ago that was a big hard drive for most people.)
 
What I suggest is this: Work out what your most important documents are and save them to one easy-to-remember folder. Weed it out ruthlessly. Don't worry about contacts and calendars and stuff like that if you have a Palm or Pocket PC, since they're already duplicated on PC and hand-held devices (and if they aren't, you should be ashamed of it, at your age). If all this weeded data comes to more than 100 megabytes, you can always compress it into a zip file, which works particularly well with bloated document formats like Microsoft Word. For this try WinZip from www.winzip.com, or the more complete PowerDesk from Ontrack International at www.ontrack.com that I mentioned a few weeks ago.
 
Now for the neat bit. A couple of years ago a Singaporean company called Trek 2000 International (www.thumbdrive.com) started selling mini-drives about the size of your little finger, which they called ThumbDrives (don't ask; probably they all have small thumbs down there at Loyang Industrial Estate). These sleek little gadgets look like a small lighter and slot into your USB port. After installing some software, depending on what kind of operating system you're using, you have a new drive.
 
When they first appeared they were pricey but now with competition from elsewhere they're pretty reasonable: I picked up a 128-megabyte M-Drive from Taiwan's Star King Technologies for about $80. And Britain's Targus does a more expensive 64-megabyte model, which retails for $120 and looks more like a magic marker.
 
All models, however, are well designed and fit easily onto a key ring. Which is exactly where I suggest you put it once you've backed up all your important data. Now you have a copy of all your most important stuff with you at all times -- as long as you don't lose your keys or get amnesia.
 
There are other options: If you have a gadget that hooks up to your PC, such as a camera, MP3 player, Pocket PC or Palm, chances are you can store data on the flash card that comes with it. Hook the gadget up to your PC and you should be able to read the contents of the flash card as a separate drive. In most cases you can now put anything you like on it.
 
In the future this will be how most of us store all our stuff: M-Drive promise a 2-gigabyte version in the near future, and while it may not be that cheap, knowing that a back-up of everything you hold dear is locked into a little finger in your pocket may be worth the expense.
