Awesome backup application

The other day I spoke with a friend of mine, who told me about Cobian Backup.
It's free, and very powerful. http://www.educ.umu.se/~cobian/cobianbackup.htm
It can be installed as a application or a service. With the service feature, you get a remote control app to you can connect to the server with. So in case you want to have backup jobs running on a server, those jobs can easily be managed from any workstation with the remote management app.
It uses 7 zip to compress the backup files, and several encryption functions including cert base RSA-AES 1024 bit. Today I installed it as a service on my Windows 7 box, and scheduled a backup of my profile. The job setup is pretty easy to use, and the job run a full backup followed by 6 differentials. It keeps 10 full copies before it starts automatically cleaning out the old archives.
Excellent logging features, lightweight and easy to use. Thanks Luis Cobian for an awesome app.
