Robert -

I use rsync a lot to keep two (or more) filesystems in sync.  It is 
not a standard solaris command, but is available all over for Solaris.

You can rsync directly from fs to fs.  For example, I'll use

rsync -aq --delete --rsh=ssh /some/local/dir/main-dir  SVR2:/some/remote/dir

This will sync over all updates to files, remove files on the remote side 
that no longer reside on the local side, do it all over ssh, is quiet, and 
maintains all the good stuff (file perms, dates, etc).  Change the q to v 
in the -aq option if you want to see the output.

Yes, you can use the filesystem while this operates.  In fact, I will sync 
certain filesystems every 1 or 2 hours just to keep them "relatively
current" 
for things such as reporting when you don't need EXACT real-time, for batch 
processing, and for backing up.

Is rsync a standard solaris command?
Can you give me an example rsync command such as:
/usr/sbin/rsync -x /dev/dsk/c0t1d0s0 /dev/dsk/c0t2d0s0
A man page snip would be great.
Can you use the file system while it is being rsynced?

Thanks,
