Hi kauczu,
Do you have multiple partitions on that disk? (1 for /opt, 1 for swap, 1 for /tmp/harddiks)
if so, a backup can be easily made by:
make sure none off the services are running..
(prevent services from starting up by uncommenting the line in the post-boot file)
like this (in your /usr/local/sbin/post-boot file)
then flash it, and reboot.Code:# Run all active services - active means starts with S #/opt/etc/init.d/rc.unslung
after the reboot you will be able to login in with telnet/putty.Code:flashfs save && flashfs commit && flashfs enable && reboot
then run the following command: (which makes a *.tar.gz file of the /opt contents)
(replace /tmp/harddisk to the mounting point you have mounted your data partition to)Code:tar -cvzf /tmp/harddisk/opt.tar.gz /opt
full procedure can be read here: http://www.wl500g.info/showthread.php?t=12812
(procedure also has the code to restore the opt.tar.gz file to the /opt partition)
