does the c8x0 in r121 get flashed with a initrd.bin file or a similar file with a different name?
if yes, what does the following show:
head -c 10 initrd.bin
if it shows
then it probably is possible to use zbackup to generate a flashable backup.. but of course all this is theory until someone actually tests it since I can't do it without one of those
Nope, no dice. Besides the separate bootloader required (which I wouldn't expect to be backed up anyway), the install files are in two separate pieces, a kernel.img & a rootfs.img. oh well.
What I'm trying to do is create a tarball of my rootfs & use that to restore. As far as I can tell it's failing because tar is dereferencing symlinks & thus create an image that's too big, but I'm not sure yet.
Another idea I've thought of is using rsync to sync the rootfs & a backup directory on a card. That way even files that had been removed from the base image (say, uninstalling a package) would be accounted for. Haven't had time to do any testing with that yet. The only 'issue' I can think of would be that I don't think rsync is included in the base image (it's been a while, so I'm not sure), so that would require installing it before restoring the backup.
