When I used to do tech support for a certain computer company with a fetish for cow spots, one of the things I was often asked was “how do I share my data?” It’s something my husband, the network engineer, has to deal with on a daily basis. How do you safely share files, back up critical things, without resorting to less-than-great security, or easily misplaced flash drives? The other question was, “My computer crashed, how do I get my files,” to which our first response was always, “well, did you back up?” You’d be surprised at how many people said no.

An excellent solution for this is an online backup service, such as iDrive. For no money at all, you get access to 2 GB of space on their server. For $4.95 a month, or $49.95/year, you get unlimited storage space. It’s enough to back up all the data on the average PC (something most people don’t do, but which everyone ought), or share files with remote users in Rome, Paris, San Francisco, Tokyo, and Dallas, without allowing remote access to your own machine.

Even if you already have the contents of your hard drive backed up, iDrive is great as a backup solution. I’ve always been told that crucial data should be backed up multiple times, with at least one copy stored off-site. This is a great way to do that, without having to make periodic trips to dusty storage units, or remember which file cabinet in the office holds your disks. Also, since they have almost-instant backup of their own servers, your data is doubly secure.

Even if you don’t use iDrive, make sure you back up your data on a regular basis.

But if you travel, share files, or live in a place prone to electrical failure, consider iDrive. iDo.

(One thing: iDrive isn’t Mac-Friendly.)
