To create a backup

dd if=file1 of=backup.dd

Everything is file. IF = Input File, OF = Output File. So, you can clone an entire disk

  • Use bs=4096 argument if you are cloning into a HD and need more speed on process
  • Use status=progress to monitoring data written
  • Use conv=sparse to sparse file
  • For integrity: sha1sum backup.dd & sha1sum file1

Mount

To browser and see files

mkdir /media/file
mount backup.dd /media/file

dd if=disk.dd of=/dev/sdb

Hi!
In this method, you can see "folder" as "file".
folder == file

Hope it still working!

Nope it doesn't. It reports an error saying it's "a folder".
