I use Win32 Disk Imager to backup my Pi. Works well.
I was wondering if it is possible to perform dd command of SD card where Raspbian is up and running. Any clues if that will do exact copy as Win32 does? Or some file might be missing as used by system? I am new in Linux...
Would be much easier if i could just take the .img file via Samba. Also my Pi uptime would not be disturbed. Thank you.
