I read different howtos on the wiki and oracle docs, but I can't get it to work: legolas:/mnt/btrfs_pool1# btrfs subvolume snapshot -r tmp tmp_read_only_new Create a readonly snapshot of 'tmp' in './tmp_read_only_new' legolas:/mnt/btrfs_pool1# sync legolas:/mnt/btrfs_pool1# btrfs send tmp_read_only_new | btrfs receive /mnt/btrfs_pool2/ At subvol tmp_read_only_new At subvol tmp_read_only_new # Make a new snapshot later and try to sync it: legolas:/mnt/btrfs_pool1# mv tmp_read_only_new tmp_read_only legolas:/mnt/btrfs_pool1# btrfs subvolume snapshot -r tmp tmp_read_only_new Create a readonly snapshot of 'tmp' in './tmp_read_only_new' legolas:/mnt/btrfs_pool1# btrfs send -p tmp_read_only tmp_read_only_new | btrfs receive /mnt/btrfs_pool2/ At subvol tmp_read_only_new At snapshot tmp_read_only_new ERROR: creating snapshot tmp_read_only_new -> tmp_read_only_new failed. File exists This is where I get stuck: Obviously /mnt/btrfs_pool2/tmp_read_only_new already exists since it's the reference backup volume. What am I doing wrong?
