10. Carbonite, which is priced at $49.95 per year for unlimited storage for any desktop, laptop or handheld (software download included), can configure to back up in off-hours. Carbonite installs a small application on the computer that works unobtrusively in the background, looking for new and changed files that need to be backed up. There is no new interface to learn. Highly recommended.
11. MozyHome also works unobtrusively in the background, backing up files as they are saved. Pricing is $4.95 per month, with unlimited storage for any desktop, laptop (PC or Mac, by the way); the first 2GB of storage are free. Software download is included, and it can configure to back up data during off-hours. Parent company EMC is now integrating into it highly regarded RSA encryption security, which is a welcome feature. Highly recommended.
12. Box.net works similarly to MozyHome and Carbonite. It comes with various pricing plans: 1GB free accounts are available; it costs $7.95 per month for 5GB in the individual starter plan; and prices range up to $19.95 per month for 15GB in Professional plan. Box.net focuses heavily on file sharing; you can share and send any type of file-including documents, photos and videos that are too large for e-mail. Recommended.
If you are looking for remote access to your files from multiple computers, cell phones, or online applications such as Linkedin, Ning, Netvibes and Facebook, consider using Box.net. You also can edit photos and images online with Picnik, work on your Word and Excel files using Zoho, and preview documents with Scribd's iPaper. There's no software to download.
13. Amazon S3 (Simple Storage Service) provides a simple Web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the Web. It was originally intended for software developers, but anybody can use it. It offers developer access to the same highly scalable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of Web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
Pricing is on a sliding scale, with charges for storage capacity (starting at 15 cents per GB per month for the first 50TB of storage) and file transfer (starting at 10 cents per GB). See Amazon's Web page for more information.
