Have looked at and tried to do
full backup of rootfs -- it kept flooding the file with 0xFF after some moment.

I killed it at size of 200M

apparently I was in NOR flash with u-boot 1.3.2-moko12 from May 9th

and on my box cmd line looked like

*$> sudo  -a rootfs -R -U backups/20080728/rootfs.bin
