I think you're right. cat will churn the whole file, you need some alternative that is sparse aware. The best approach would be: qvm-run --pass-io tempDebian 'tar -Scf - /home/user/meta.raw' > meta.tar and then untar the resulting file Almost anything else (dd, rsync etc) will have some overhead in my experience. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
