Backup Image from GL-AR150


Im looking If is possible to create and image from the sensor, a .bin file that restore router when interested.

I saw imagebuilder, but I can’t find If exist option to make and image from environment


Im checking sysupgrade, but this system only backup config. My plan is If is possible to do a backup bin. I found some references but in this case my router is a GL-Ar150 so very simple and If I would like to use dd command I don’t know how to exec.

Other option is this command

cat /dev/mtdblock5 > /tmp/firmware.bin

but Im not sure If I do after

sysupgrade  /tmp/firmware.bin

will recover all config setup and files.

Any suggestions?
