rsync remote-to-remote is not supported
Referring to source and targets for rsync, course material says:
both may be remote
Yet, when I RTFM on"Ubuntu 18.04.5 LTS" , it says otherwise:
Rsync copies files either to or from a remote host, or locally on the current
host (it does not support copying files between two remote hosts).
Testing on an Ubuntu 20.04 system:
$ rsync -va host1:/tmp/rsync.remote-to-remote.test [email protected]:/tmp
The source and destination cannot both be remote.
rsync error: syntax or usage error (code 1) at main.c(1303) [Receiver=3.1.3]
Gotta admit, it would be a nice feature to have instead of
