Re: ssh_args

Cole,

I think your problem is with this part:
        --rsync-path='sudo /usr/bin/rsync' 
of rsync_long_args.

Rsnapshot (up to and including 1.2.9) does not recognise quotes when
breaking up the arguments into words, so the list of words fed to exec 
probably looks like this:
        /usr/bin/rsync
        -alptgoHuv
        --delete
        --numeric-ids
        --relative
        --delete-excluded
        --rsync-path='sudo
        /usr/bin/rsync'
        --rsh=/usr/bin/ssh -p 2222
        net-backup@A:/etc/
        /root/backup/snap/daily.0/etc/

The CVS version of rsnapshot has had some work put into improving this
quoting issue (thanks to David Cantrell). 

But instead of using the CVS version or waiting for the next version, I
would suggest the easiest thing is for you to create a shell script that
just consists of
        sudo /usr/bin/rsync "$@"
and use that shell script as your --rsync-path.

You might also want to use rsnapshot version 1.2.9 which is available
in Debian "testing" (since 2006-06-20) rather than 1.2.1 (in "stable").
