This is the most basic of cloud services and is offered to even the smallest user. It allows you to back-up your data over the Internet to a secure hosted data centre. This is disaster recovery for the masses – if you lose, damage or destroy your computers or files, a copy of your data is held safe for you. The service is relatively inexpensive and security is usually good – your files are encrypted before you send them.
Things to consider include: can you get access to your backups via the web, how much can you store and do you want backups automated?
