I was trying to dd a laptop drive to an image file on a NAS drive and managed to fill up the / partition.
I've now fixed that but in order to avoid the same problem, can somebody tell me how to duplicate a drive, or at least the recovery partition (it's a Windows drive) by specifying where the temporary file can go? Or if there's a way to do it without generating an intermediate file it would be appreciated.
Unless I misunderstood you, this should never happen.
Man dd has no mention of using temporary files for any transfers of any kind.
I even straced dd by copying one large file from one partition to another partition. No mention of temporary files in the strace log (tho I did check only the open() syscall, and syscalls at the start of the program when the source and dest files are opened).
Perhaps your NAS is working incorrectly?
