This is the software publisher's description.

Data backup solution for home PC users which protects digital photos, music and any other files from damage or loss. Webroot Secure Backup, delivered over the Internet as a service, automatically secures data online, locally or both to ensure users always have access to the files they value most.

Webroot Secure Backup combines online and local data protection into a single, simple application and service that provides up to 50 gigabytes of online backup space and protects files on up to 3 different computers; making it ideal for families and power-users alike. Users are able to select what they want saved by using simple tree indexes that allow them to pick either files or full folders for backup.

Webroot utilises one of the most advanced three-tiered file encryption processes available to consumers to ensure privacy and data integrity, and leverages multiple tier-IV data centers to keep files secure “in the cloud”.

No other backup provider delivers the support of Webroot’s global data network. Data backed up online is accessible from any PC with Internet access, and users can easily share links to files rather than send large e-mail attachments. Users can also create secure backups on local media such as CDs, DVDs, external hard disks, and flash drives.

Note that you need to register with Webroot, and open an account, before you can use this software. You'll receive 2GB for 30 days as part of your trial.
