Seems that I did not consider the realistic need for space when using ISR. I have done my first snapshot but basically have not enough space available on my HD to do further snapshots. My second harddrive does not hold the capacity either and using the network to go further is extremely slow. I am not even talking about super huge files (only approx 13 GB) Any options apart from upgrading my system? For the moment I guess one secondary Snapshot may already save me but obviously this would not really take advantage of FD-ISR.
