rsync --partial --progress -e ssh archivo.txt usuario@192.168.1.100:/ruta/al/destino

Simplificando:

rsync -P -e ssh archivo.txt usuario@192.168.1.100:/ruta/al/destino

-P: combina las opciones –partial y –progress en una sola, simplificando así la escritura.

-z compress file transfer
-t preserve time (other attributes as owner or permissions are also possible)
-P resume incomplete file transfer
-r recursive into subdirectories
-v verbose
