Storing movies, photos, music and online data is convenient. But it can also be imprudent. Our tips for enjoying the cloud, without clouds are the followings. The numbers are dizzying: at the end of 2014, there were about 300 exabytes of data stored in the cloud worldwide, or 7% of the data produced on Earth.

The equivalent of 450 billion DVDs, 90,000 billion photos or MP3s or 37 billion pages of text! It is estimated that one in five Europeans already uses the cloud to save files and share them. Cloud computing is the ability to access remotely and from any device files (email, calendar, photos, music, videos), which are no longer saved in the memory of your computer or your smartphone, but on a powerful central server.

Problem: You must have an Internet connection, and the data stored online is potentially piratable. So, in September, hackers managed to penetrate iCloud servers, the Apple service, to steal the nude photos that celebrities had placed there. Very personal shots of the actress Jennifer Lawrence or the singer Rihanna were found on social networks. With the good at cloud hosting you will have the best deal now.

On the business side, the cloud makes it possible to use online software without having to install it on all the users’ workstations. Another advantage: do not have to invest regularly to increase storage capacity, at risk of becoming overcapacity thereafter. There is only to adapt the package to the needs.

  1. Is it safe?

Overall, yes. But in the same way that you can have your email password stolen, the cloud password can be forced. The best way to protect you is to choose the right mix: it must be complex and not used for other services.

  1. Can everything be stored in the cloud?

Since the cloud is not foolproof, any potentially sensitive data should not be there. Ask yourself if a document in the nature could harm you. That a stranger uncovers your pay slip will not change your life. If he has your RIB in his hands, it’s more embarrassing.

  1. Where are my data actually stored?

In huge data centers spread over four continents. In Europe, Microsoft and Google have one in Dublin, but nothing says that this is where the European data goes: they can very well be stored on the US territory. Your data may also have been copied to multiple centers, to prevent them from being lost in the event of an incident.

  1. What is a digital safe?

 

Most banks offer secure clouds, mainly to store administrative documents that you want to keep. You can send certain documents directly by their sender (EDF invoices, pay slips, etc.) to this virtual safe. Their digital copy will then have the same legal value as the original.
