I agree with that reasoning. In any case, I think that the btrfs clone operation should be disallowed in ecryptfs as a matter of urgency (upstream as well), since it can result in data loss, which is far worse than the (presumably small in practice) disk space savings available though using the clone. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1305335 Title: Cutting or copying files on btrfs to ecryptfs results in data loss Status in eCryptfs: Confirmed Status in The Linux Kernel: Unknown Status in linux package in Ubuntu: Confirmed Status in nautilus package in Ubuntu: Invalid Bug description: I've installed a fresh copy of 14.04 beta 2 on a brand-new SSD. I used btrfs as the filesystem. I set up a Private folder usying ecryptfs-setup-private. I copied a few folders into the Private folder, and the entire directory structure and subfolders are copied, including the files themselves, yet every file contains 0 bytes. However, I can create and save new files in the Private directory. Also, folders and files can be correctly copied if I use the command line cp -R.
