copy only missing files

[Abstract]

Hi Everyone,

I'm looking for a command to only copy the missing files between a source and destination.
A copy between a source and destination on the same hard disk failed due to ssh connection interruption. I've search at google but no luck yet. Does anyone know a solution?

net/rsync.

I use rsync almost exclusively whenever I want to reliably transfer data.

Perfect, I'll use rsync for it. I thought there maybe were other commands to do it beside rsync.

there's also sysutils/cpdup
