I've been trying to set up an OpenSolaris-based NAS server, with one of its 
functions being a backup server for my Mac-based network. I'm using rsync 3.0.3 
pre2 on my Macs with some extended attribute patches, but have been running 
into some compatibility problems when rsyncing via SSH from a Mac to the 
Solaris server (I’m not running daemon mode on the server, but rsync 3.0.3 pre2 
is installed and in the bash path). For example, running “sudo 
/usr/local/bin/rsync -a -z -e ssh "Backup Source" "[EMAIL 
PROTECTED]:destination" --exclude-from=/Users/.rsync/exclude --delete-excluded 
--progress --dry-run” allows my Mac’s rsync to successfully push data to the 
Solaris server. However, when I add some extra flags to support the Mac’s file 
attributes, specifically -AX and --fileflags to preserve ACLs, xattrs, and 
Finder file flags respectively, I receive the following errors:

When calling --fileflags:
$ sudo /usr/local/bin/rsync -azx -H -e ssh "/Users/Documents" "[EMAIL 
PROTECTED]:/Target_Directory/" --exclude-from=/Users/.rsync/exclude 
--delete-excluded --fileflags --protect-args --progress --dry-run
rsync: on remote machine: --fileflags: unknown option

rsync error: error in rsync protocol data stream (code 12) at io.c(635) 
[sender=3.0.3pre2]

When calling -A (ACL’s):
$ sudo /usr/local/bin/rsync -azx -HA -e ssh "/Users/Documents" "[EMAIL 
PROTECTED]:/target_directory/" --exclude-from=/Users/.rsync/exclude 
--delete-excluded --protect-args --progress --dry-run

$ sudo /usr/local/bin/rsync -azx -HX -e ssh "/Users/Documents" "[EMAIL 
PROTECTED]:/Target_Directory/" --exclude-from=/Users/.rsync/exclude 
--delete-excluded --protect-args --progress --dry-run

rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(635) 
[sender=3.0.3pre2]

It appears that even though I’m trying to perform a “push” operation with rsync 
(without using the remote demon), the SSH connection seems to still be calling 
rsync on the Solaris server and is running into some error. Is there a rsync 
flag to not call rsync through SSH on the target server?

It’s also possible that the error is coming from a lack of support of either 
Solaris/ZFS ACL’s or xattrs in rsync itself (I compiled the fileflags patch in 
rsync on Solaris, so I’m not sure why this wouldn’t work other than maybe the 
patch’s code only supports Mac?), or a general lack of compatibility between 
the Mac’s extended attributes/ACLs and ZFS’s extended attributes/ACLs. However, 
I've played around a little with the Mac OS X ZFS implementation which seems to 
have no problem handling metadata, but I'm not sure if the support is exclusive 
to the Mac implementation or if it is present in ZFS in general. Any help on 
how to fix this issue or successfully back up a Mac to a ZFS host via rsync 
would be greatly appreciated! Thanks!
