mhm there is nothing special. But i try to provide more information / a
small howto:
# mount |grep btrfs
/dev/sdb on /btrfs/src type btrfs (rw)
/dev/sdc on /btrfs/target type btrfs (rw)
# btrfs subvolume list /btrfs/target/
# btrfs subvolume list /btrfs/src/
ID 277 top level 5 path @snapshot/1
ID 278 top level 5 path @snapshot/2
ID 288 top level 5 path @snapshot/3
# btrfs send /btrfs/src/\@snapshot/1 | btrfs receive
/btrfs/target/\@snapshot/
At subvol /btrfs/src/@snapshot/1
At subvol 1
#
Now i was trying to send an incremental snapshot:
# btrfs send -i /btrfs/src/\@snapshot/1 /btrfs/src/\@snapshot/2 | btrfs
receive /btrfs/target/\@snapshot/
At subvol /btrfs/src/@snapshot/2
At subvol 2
ERROR: failed to open /btrfs/target/@snapshot/@snapshot/1/test.tar. No
such file or directory

Greets,
Stefan
