Reliable(-ish) rsync

Sometimes I have unreliable connection, but rsync (nor rclone) don't support automatic resumption of a single file.

$ rsync -P file1 remote:
file1
     34,358,880  79%  301.00kB/s    0:00:30  client_loop: send disconnect: Broken pipe

rsync: [sender] write error: Broken pipe (32)
rsync error: unexplained error (code 255) at io.c(848) [sender=3.2.7]

I've created simple script that gets the job done. Feel free to copy it to your $PATH (~/.local/bin or /bin)

$ rsync -P file1 remote:
file1
     34,358,880  79%  301.00kB/s    0:00:30  client_loop: send disconnect: Broken pipe

rsync: [sender] write error: Broken pipe (32)
rsync error: unexplained error (code 255) at io.c(848) [sender=3.2.7]
rclone failed. retrying...
file

OK

rtsync.sh

#!/bin/bash

until rsync --partial "$@"
do
  >&2 echo "rsync failed. retrying in 5s"
  sleep 5
done

echo "OK"
