rsync - Apr 2012 - Problem syncing to Netapp (rsync: failed to set times on...)

Hey folks.

I have a machine that I use as an intermediary to rsync between a NAS in 
another building (the users there have poor bandwidth and need local 
storage) and the our Netapp located in our Datacenter. I get lots of the 
"rsync: failed to set times on..." errors, and files which have
already
been transferred just try to sync again anyway.

These are the mount options that I use for both sides:

mount -t cifs -o credentials=/root/.synccreds //nasdevice/folder /nas
mount -t cifs -o credentials=/root/.synccreds //netapp/folder /netapp


The ".synccreds" file has the credentials of an Active Directory
Domain
Admin account, which has "Full Control" on both the NAS and the
Netapp.


Here is the command that I run to do the rsync:

rsync -rvt  --delete --progress /nas/ /netapp/

Running rsync with "-i" shows that the files are transferring because
of
timestamp differences.

I tried the "-c" option in place of the "-t", but the server
doing the
sync just hung there for literally two days without anything transferring 
and no output. I realize that the -c option is slower, but yikes!

Any thoughts? Suggestions?

Thanks,
Bill D.

PS: Another (ugly) workaround: Use two linux boxes, place then both on 
each side of the slow line. One side having the NAS mounted + running 
rsync server, the other having the netapp mounted.
Then sync between those two linux boxes. Even if you have to use -c or 
--ignore-times the "full read just for checksum" would only happen in 
the LAN of each networks while the slow line has only the burden of the 
checksums and actual transfers.
