When using the dd command the source and target drives/partitions:
- must not be the same
- must be unmounted which means that one has to boot up from a drive that does not involve the source or target
Creating a cloned partition:
dd if=/dev/<source partition> of=/dev/<target partition> bs=4096 conv=notrunc,noerror
Creating a compressed image file of a partition:
dd if=/dev/sda1 bs=4096 | gzip > partition.image.gz conv=noerror
