dd / ddrescue Question
Posted: 29 Dec 2013, 04:35
I would like to backup/clone/copy a failed partition to a file under Linux, and be able to reverse the process if needed. Reading the ddrescue documentation, it seems that partitions can only be copied to other partitions, and the dd documentation is ambiguous on this as well. Will this create a good backup of a my partition to a file?
>dd bs=512K if=/dev/sda /home/me/bup.dd conv=noerror
or this?
>dd bs=512K if=/dev/sda2 /home/me/bup.dd conv=noerror
Also, will it do any damage if I get the block size wrong? Thanks!
