That sounds really good but is that safe to do? I thought you shouldn't dd a disk if there was some activity going on on it.
So is the output image saved to the SD card or do you save it to an external drive?
Been working fine for me for several years.
You can have it written to an external drive, or you can use tools like sshfs and ftpfs to mount remote servers as local drives then write to those. I use the sshfs route.
This will create an .img that you can just write directly to an sd card and boot from.
Very cool, thank you.
