I have converted a large ext4 filesystem to btrfs and by accident

First, you should never try converting important data without a backup...
What I've read seems to be telling me to mount the subvolume
ext2_saved and then mount the image file residing in that directory.
I am VERY new to btrfs and am seeing some troubling output (see below).
Here's what I've done and what I'm seeing. Could someone help me with this
please?
ls -al /ext2_saved

fc35-bash 5.1 ~# mount -t ext4 -o loop,ro /ext2_saved/image /ext4

I don't know much about btrfs, but what does "file /ext2_saved/image" say?
