hi Craig
here some explanations:
i set $Conf{ClientTimeout} to 600, 10min
i try to transfer dir with one long file ~7Gb on slow link ~1MB/s
so after 10min of transfer rsync_bpc receive ALARM and terminates
i think there no output during file transfer, this behavior noted in doc
but not clear, only smbclient mention
and i think this behavior not handy and not funny, i need "true" timeout on
io hangs
why i set $Conf{ClientTimeout} to 600 ?
there another problem
i test network failure during file transfer, i just terminate interface on
server (ifconfig down) and after ~5min up
so, on client side there send error detected and tcp connection terminated
by OS
on server side tcp connection just hang, rsync_bpc hang and backup process
just hang,
it bad idea (i think) wait 72000 to start new backup session
what about parameters to rsync_bpc? --timeout -z ?
