When I tried to run rsync (3.1.1) on my FreeBSD box today, the following message caught my attention:
#rsync -avzr --rsh="ssh -c arcfour" --delete --compress-level=9 sourcemachine:/source/ /target/ This rsync lacks old-style --compress due to its external zlib. Try -zz. Continuing without compression.
Basically, rsync suggests that you should use the -zz option instead of the old style option. So I gave it a try, and of course, I got something like this:
#rsync -avr --rsh="ssh -c arcfour" --delete -zz sourcemachine:/source/ /target/ #My target machine is CentOS / rsync (3.0.6) rsync: on remote machine: --new-compress: unknown option rsync error: syntax or usage error (code 1) at main.c(1422) [server=3.0.6] rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.1]
The reason why we have all of these messy things because there is a bug in rsync 3.1.1. (rsync –version) To solve this problem, you will need to rebuild the rsync by skipping the ZLIB_BASE option:
cd /usr/ports/net/rsync sudo make config #Uncheck the ZLIB_BASE option sudo make reinstall clean
Now the rsync should be happy.
