I seem to have changed the syntax since I wrote this. I have definitely used it to install jffs2 images:
  boot> vfat ls
  boot> copy hda1:task-bootstrap.jffs2 root

It should also work for backups:
  boot> copy root hda1:backup.jffs2
with the caveat that bootldr can only update files that already exist -- it cannot make new directory entries. Patches to fix that would be accepted.
