For those of you who need to “resume” SCP file transfers that have been interrupted, there’s an easy way to resume them using rsync command.
Use this:
alias scpresume="rsync --partial --progress --rsh=ssh"
For Ubuntu or Debian add sudo:
alias scpresume="sudo rsync --partial --progress --rsh=ssh"
This is great since you won’t have to restart your file transfers if you happened to be transferring files around 100GB.
Perks include understanding the same user@host:path syntax as scp as well as being able to resume a broken scp download (Note: I’m not guaranteeing this, but after downloading 90% of 400MB I was able to pick up the rest using this).
