Converting btrfs back to ext2/3/4

If you convert a ext2/3/4 to btrfs with btrfs-convert you get a snapshot/subvolume containing your ext2 fs. An Image.

If you delete this image you cant use btrfs-convert -r to roll-back to ext2/3/4

now my question.

Is there any way to create this image with an existing btrfs? So to roll-back to extX without an exisiting image of it.

I doubt so based on what I've read. Have not used/tried it yet, so YMMV.

You answered your own question. If the image doesn't exist, you can't convert btrfs back to extN.

Of course you can - just not directly.

Do you really need that image or wouldn't it be ok to just tar the filesystem, store it elsewhere, create new file system and untar it?
