Hi,
I'm also interested in this, although my configuration ( SL-6000 ) has no hard drive,
so an image copy of my SD as well as a NAND restore should be sufficient.
Many (and I mean many) years ago, I spent quite a bit of time researching a
complete backup solution for a couple LINUX laptops. I ended up needing to
create a minimal boot system with the restoration software (I believe I ended up
using taper) as well as tar, a kernel with ZIP disk support, etc..
I suppose I would be in the exact same boat as the C-XXXX users if I ever purchased
a CF microdrive, but I have never toyed with the clamshells or multiple-boot configurations
on the SL-6000. I suppose a method to NAND-restore a minimal system, that could
perhaps read from SD or CF and restore to the HD would be cool, then after the HD
was restored, a NAND-restore of the full system could be performed. Of course the
backup-side of things to backup a HD to multiple CF/SD cards would be needed as
well. Just some thoughts... John
