Hi there all

I couldn't find related post to my questions.

In odrer to keep my devices working when repositories go down for good, or any other bad thing will happen I would like to make images of (For example my Nokia 770) all partitions that will include:
-System partiton (With installed programs, settings etc)
-Home partiton
-RS-MMC Card.

Is there a software that will do that? If so, how to do it? And finally how to use those images to "flash" tablet with them?

My point is to install new os on my device, download and install needed software, make device suitable for me and than make image (clone) of partitons.

If something goes wrong and my device will need flashing I would like to have already prepared os (With apps and so) to install it directly to the device.

Step-by-step would be nice, but I can work with anything.
