I use USB flash drives with ext4 for backups and have not had any 
problems with journalling. I have had at least one successful journal 
recovery, after an inadvertent disconnection before unmount. What 
problems did you encounter?

I optimised my ext4 backup filesystems for a small number of large files 
(compressed archives) with:

mkfs.ext4 -J size=4 -m 0 -T largefile4 -O "^resize_inode" /dev/sdb1
tune2fs -c 0 -i 0 -L Backup /dev/sdb1

My /etc/fstab contains:

LABEL=Backup /media/backup ext4 noatime,noauto,user,errors=remount-ro 0 0

Kind regards,
