Thank you for your answer.
I quoted the post by KonstaT on purpose.
I'm just looking for a procedure to save the current ClockWorkMod recovery in a file like recovery.img. The partitions/folders /boot, /system, /data, /cache are saved by the backup itself. There's no need to save it with another method. The only missing thing would be /recovery. But I was hardly looking for something like this without success. I couldn't find a partiton/folder named /recovery.
Then you say just told me before ... it's called NANDROID. Even this I was hardly looking in your post yesterday. It has just one sentence without NANDROID. And it's not what I'm looking for, too. This just make a backup without rebooting in recovery mode or a recovery image in boot itself. But I want a recovery image. I'm just looking to backup it ...
I just tried NANDROID on my old ZTE Skate. It saves a recovery.img, which looks good. But the saved recovery.img is 5.242.880 Bytes, whereas the uses recovery.img I flashed to this phone about 2 years ago ist just 4.536.320 Bytes. So I'm still not sure, if I really can rely on this image file...
On my Linux system I make backups using the "dd" command. I hardly remember using a command like "flash" or something to save the old recovery.img to the phone. The "dd" command ist quite simple to invert with the switches if= and of=. This is what I'm looking for.
