How do you backup your critical data? Traditional backup procedures use regular copy sessions to tape, disk or CD-R/DVD-R media. The broadband internet allows companies to provide online backup services. Such online systems can easily scale and provide cost effective remote backup for a wide range of customers. However they are definitely not one-size-fits-all.
Consumer oriented online backup offering such as Carbonite, Mozy or XDrive has a typical price of ~$1/GB/month although limited free services are available. Check out this review on ars technica for details.
Another solution is to use the Amazon Simple Storage Service (S3) with the s3sync tool or the Amazon S3 Firefox Orgainzer plug-in (S3Fox). Pricing ($0.15/month for a GB of stored data) is really attractive compared to the above services.
