So here's what's happening.
I started a backup of a drive on my server through a Linux live USB. I started copying the first drive with the
dd command vanilla; just
sudo dd if=/dev/sda of=/dev/sdc1 and then I remembered that this just leaves the console blank until it finishes.
I needed to run a different backup to the same drive anyway, so I started that one as well with
sudo dd if=/dev/sdb of=/dev/sdc3 status=progress and then I got a line of text that shows the current rate of transfer as well as the progress in bytes.
I was hoping for a method that shows a percentage of the backup instead of doing the math of how many bytes are backed up out of 1.8TBs. Is there an easier way to do this than status=progress?
