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.

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.
