Online backup with CloudBerry Online Backup
Everyone needs to backup their own personal data. The question is more how to take good backups. Many people I know just copy their data to a second harddrive and find that suffient enough for them.

I know there are many online backup solutions. Most of them stores your backup in their own “cloud”. But there is a new breed of backup software now that lets you backup to the cloud of your choice.
What is CloudBerry Online Backup?
In short terms this is a Windows software that backs up your computer, placing the backup in a storage of your choice. It can be a local filesystem (like a secondary drive) but it can also be your favourite cloud like Amazon AWS(both S3 and Glacier), Google Storage or Azure.
You have all the features you expect to find in a backup software like versioning, point-in-time restore and so on.
How does it perform?
I have it running on two computers myself, backing up about 500GB in total. It does not slow down my computers. I have decided to keep a daily backup (as opposed to real-time backup).
Complexity
Is it more complex to set up this type backup? Compared to many online backup solutions (like Jotta, Mozy and Crashplan) it is as you will need to create and maintain an account with your cloud-provider. For me the benefits of this backup configuration makes it worthwhile.
