Hi, thank you for your response.
At the moment I don't use disk images. Instead I use LVM volumes which are directly connected to my KVM-machines. There is a way like creating images of the LVM volumes with a image tool like partimage. These images would be compressed like 50GB in combined size, no problem to copy it to an external usb drive but much data to transfer over a VDSL50 internet connection. The point is that the customer wants me to backup the whole system (real-server including 2 VMs) over the network to a different location. So when the server gets unusable damaged for instance by beeing flooded with water because of a pipe-break, or the system gets stolen, I should be able to buy new hardware and get back to the state one day before the disaster occurred. I like the efficient way of file based backups backupPC uses, so I ask for experiences on that. But maybe I should search for a partition image tool that supports incremental backups. I only know of Acronis True Image but this is a commercial (and not cheap) way.
