Anyway: I have read loads of documents but did not find an answer for sure. Even though I assume I am right. On a btrfs filesystem created; is it possible to have subvolumes with data duplication and another subvolume without (resp. with just metadata duplication)? I have some large filesystems currently with ext4 and I am thinking of changing to btrfs. Some of the data is more important than others. So I want to have data duplication on the important files (sorted in a mount point) and without for the other subvolume. So I want to have the advantage of redundancy of important files combined with the flexibility of the volume manager and shared disk space. Possible? GReetings Christian
