You can do it from an ssh session. I use the script below

#!/bin/sh
echo "Make sure you have opkg installed mkfs-jffs2"

mkdir  /var/tmp/root
mount -t jffs2 /dev/mtdblock6 /var/tmp/root

echo "On PC side"
echo
echo "ssh root at 192.168.0.202 \"mkfs.jffs2 -d /var/tmp/root -e 128 --pad
--no-cleanmarkers -x lzo\" | pv -W > rootfs_backup.jffs2"
echo "scp root at 192.168.0.202:/boot/uImage kernel_backup.bin"
