[rsnapshot-discuss] rsync error

[Terry Barnum]

This is not specifically an rsnapshot question but I'm hoping someone might have some insight.

I have a MacBook Pro user who updated to 10.11 which prevents (even root) from writing into /usr/bin. On previous OSes I used to copy a somewhat current version of rsync (3.0.7) in there and symlink rsync to it. No problem I thought, I'll copy it into /usr/local/bin/ instead which is really where it should've gone anyway. Doing an 'rsync --version' on the MacBook Pro shows 3.0.7 so /usr/local/bin/ is in the path prior to /usr/bin. But when the rsnapshot server runs and connects to the MacBook Pro, rsnapshot throws this error:

***@mbp:/Users/elcapuser rsync error: syntax or usage error (code 1) at /BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-47/rsync/main.c(1333) [server=2.6.9]

For some reason the MacBook Pro appears to still be running the old version installed with the OS. I can't find the above main.c path on it. Not sure what's going on. Any ideas?

Thanks,
-Terry

Depending on the context (an interactive session vs a cron job vs rsync
invoked remotely by another rsync) you'll get a different environment,
and so /usr/local/bin isn't in the $PATH. You need the --rsync-path
option to rsync, so it knows exactly which rsync to run on the remote
host. You can provide that via the rsync_long_args config option in
rsnapshot. And if you only need it on this one host you can do this:

backup what-to-backup where-to-backup +rsync_long_args=--rsync-path=...

Thank you very much David. I'll give it a try today and report back.

My MacOS 10.11 laptop user is back in town and I made the rsync-path change but I'm still seeing errors and no backup is happening.

It still looks like /usr/bin/rsync and not /usr/local/bin/rsync is being called. What am I missing? /usr/local/bin/rsync is a symbolic link to /usr/local/bin/rsync-3.0.7.

Thanks,

That's /usr/bin/rsync being invoked locally by rsnapshot ...

... and there's rsnapshot telling /usr/bin/rsync that it should run
/usr/local/bin/rsync on the remote machine.

I believe that's being spat out by your local rsync. Surprisingly, the
man page really is useful in this case.

Thank you David. I could swear I searched the man page for protocol version mismatch. I must've misplellled it, sorry.

Will try the ssh login tests with this laptop when it's back in town again.
