Problem rsyncing 450GB file to my NAS: 'connection unexpectedly closed'

[Justin T Pryzby]

Not sure, but some ideas:

-P means to retain partial files, and doesn't have anything to do with
/tmp; I wonder if you mean --inplace (not sure)?

It sounds like a daemon may be timing out; is there a timeout
specified in rsyncd.conf?  Is there a remote logfile with any useful
content?
