IF you set as destination: file:/destination-path/backup.img,

A complete image of everything will be stored in backup.img

See above. You don't have to configure anything again if you reflash your backup.img file

To get rid of LZ4 compressed extends could be (theoretically)

1) enable LZO compression
2) reboot
3) mount /dev/root /mnt for example
4) remove all existing snapshorts in /mnt/*/@-* expect @
5) create new subvols in /mnt/*/@-lzo
6) copy all data from /mnt/*/@ to /mnt/*/@-lzo
7) rename all /mnt/*/@ to /mnt/*/@-lz4
8) rename all /mnt/*/@-lzo to /mnt/*/@
9) reboot
10) mount /dev/root again and remove all @-lz4 subvols

You see, not so easy and a lot of stress for the sd-card. Backup and reflash is much easier
