Revision as of 17:46, 4 September 2023

For this experiment EXT 4 will be used (as opposed to SquashFS)

dd if=/dev/sdX of=/dev/sdY bs=512 count=1

dd if=/dev/sdX1 of=/dev/sdY1 bs=128M conv=noerror progress=status

dd if=/dev/sdX2 of=/dev/sdY2 bs=128M conv=noerror progress=status

sync

Notes;

if: Input File (or Device)
of: Output File (or Device)
bs: "How much to copy from one device to another at a time"
conv=noerror: "Don't stop, just do what I told you to do, and don't give an excuse"
progress = status: Show the progress of the copy process (only for a certain version of DD and up)
sync: Write all buffered blocks to disk (just to be safe)
If conv=sync is used an out of space error will occur.
