There Is No Absolute Guarantee
There are never any absolute guarantees whether the data will remain safe or not. So it cannot be said with 100 percent confidence that your online backup will remain safe no matter how reliable service you have taken up. However, the lack of absolute guarantee is not just the case with online backup. There are no guarantees with physical offline backup methods too. Therefore it is important that you do not rely on only one mode of backup. It is better that you backup your vital data using multiple methods.
Data Transfer From Your Computer Is Server Is Virtually SafeThe cloud computing companies are using SSL encryption which has proven to be extremely safe these days. Well you can say it is safe as long as the hackers do not find a way to crack it. However, for now you can be confident that it cannot be hacked easily. The way file transfer happens is simple. There is client side software installed on your computer from which the backup has to be taken. Then there is server side software installed on the server which will store the backup. Once you initiate the backup process the client connects with the server. The server validates the client (with username and password) and then initiates the transfer process. The transfer is SSL encrypted and thus it is virtually safe. This means nothing will intercept your data while it is on the way from your computer to the server.
How Safe Is Your Data At The Server?
This is a great question to ask. No one can intercept your data during the transfer process but is there a guarantee that no one will break into the server? Of course there is no guarantee but there is nothing much for you to worry about too. When the files are on the server, they are encrypted further using advanced encryption techniques. Cloud companies also save your data in multiple locations. So once you have transferred your data there is nothing much to worry about or lose your sleep over. Cloud computing is becoming more and more popular these days and the experts are working to make it more reliable.To conclude, you can say that online backups are pretty safe. During the transfer process SSL encryption prevents any interception. Once the data is transferred to the server it is protected with another layer of encryption.
