How do you specify which sub volume to save with BTRFS ?

I am trying to backup my data using fsarchiver so that I can move back to ext4 from btrfs.

But the problem is that I don't want all subvolumes to be saved.

I just want to save a particular subvolume, how do I do that ?

Try changing the default subvolume before running fsarchiver:

mount /dev/sdxy /mnt
btrfs subvolume set-default …
umount /mnt
fsarchiver savefs foo.fsa /dev/sdxy

See man 8 btrfs-subvolume.
