I have already mentioned Remote Backup tools here (Mozy and GMail Space, Connected.com is another expensive sample) that store a copy of the files on your local PC onto remote backup space in order to store them securely at another site.
For a monthly fee all these services offer storage of your files on their servers in their datacenter. Wherever that is. And however secure that is.
Crashplan offers another interesting alternative: You can run their software on two of YOUR PCs and backup the data from one PC (e.g. in the office) to the other one (e.g. at home or another office). The crashplan software manages the connection between the two and secures the data through encryption.
Up to now you would have to purchase expensive software (e.g. we use NovaNet Web Backup for Paessler AG’s remote backups) to do something like this.
For the simpler service Crashplan charges you a one time license fee $20 for each computer that you install the software on (and then back up). And some $60 for the Pro License with more features (Compare)…
Oh, and BTW (this one is for Bernd 🙂 ): You can even backup between PCs, Macs and Linux boxes!
