Take a look at https://qubes-os.org/doc/mount-lvm-image/ That explains how to mount an lvm image. Alternatively you could look at https://github.com/unman/qubes-sync where I outline how to rsync data over qrexec. I've updated that to include sshfs over qrexec, but don't seem to have pushed it up yet. That'll have to wait until the morning. But the principle is simple - run sshd on the target instead of rsyncd: use a forwarder, and then mount the remote directory using sshfs on the client. That removes the need to copy files around, and keeps a single archive accessible from other qubes. That should give you idea of how to get started - if you need help let me know and I'll try to help in the morning. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
