There are already two USB-disks that are swapped every few days and I copy
nightly images on the currently connected drive. Some weeks ago, the office had
a water-pipe break. The water has been stopped early enough so there was no
damage, but my customer assigned me to create a external backup solution. He
wants me to be able to completely restore the system including the virtual
machines if someone breaks into the office and steals the hardware ore
something like that. If this happens, I need at least one day to buy new
hardware. But the point is that I need to be able to restore the system
afterwards to a working state just like it was one day before the disaster
happens.
As I understand the rsync functionality the algorithm is able to do in-file
incremental updates. My problem is just that I can't figure out what prevents
it from working in my case...
