Backup/Restore Entire Disk with dd over SSH

ssh [email protected] -o Compression=no "dd bs=1M if=/dev/sdX" | dd bs=1M of=/dev/sdX

If the default block size of 512B is used, the transfer rate will be less than 30 MB/s. With an increased block size of 1MB I’m able to achieve gigabit speeds without any problem.
