Dear all, since btrfs uses cow I wonder how I can erase confidential data. Replacing the file does not work, since the new content is written to new blocks while the old confidential content remains in its old block (which may be unused now - depending on snapshots). Is there a method to overwrite the blocks of a file (if there are no snapshots pointing to it)? Alternatives are: - using encfs to save confidential data - using luks to encrypt the whole disk/partition other suggestions?
