So you re interested in online backup and you know you want to have a trial before committing. What else do you need to consider at the outset?

Let's look at contractual terms. Some providers get you to sign up for a year in advance while others opt for three months in advance. Just imagine if the service starts going wrong or the support is appalling? The scene would be set for maximum frustration and worst still you'd be wasting money.

We therefore advise you opt for a monthly contract at the very maximum. If a provider is that good, they won't need to lure you into a contract longer than one month. It is very easy to collect payment nowadays so a one month subscription isn't a problem from that perspective.

So remember - one month contract at the outset.
