I am working on an embedded Linux ip-camera. I need to have a backup of our Linux for testing and repairing cameras. I have tested multiple options like using
rsync , but it does not work and shows some errors eg.
short read and ...
The problem with
dd is I dont know what part of /dev must be copied because
fdisk -l shows nothing, and so there is not enough storage in cameras to save the backup file, and more about clonezilla is that I can’t install any beside package on cameras. I don't have SSH access and finally I have just telnet and serial port access.
What I can do to backup and clone the Linux?
