They all have different things to offer, and whilst there is a part of me that longs for the simplicity of 'one cloud to rule them all' , the reality is that they are all better at something.
Wuala has a fine pedigree having been created by LaCie, and now bought by Seagate. They offer secure cloud encrypted storage similar to SpiderOak, but their software is far more advanced. You are able to go back in time to find that old version of a file in case it gets corrupted or you need to roll back to a previous version, this is a killer feature.
As the data is all encrypted before it leaves your machine and only you hold the keys, you really can be certain that it is secure and private.
Wuala have a referrals program like most providers, and if you sign up for a free account using the link below you will start with a Free 6GB account.
