NetApp has a vol option noatimeupdate. Might it help if there is there a similar setting on HNAS? Netapp also recommends just setting it in general to increased performance on heavily used volumes.

I need to migrate terabytes of data from one NAS (NetAPP) to a new NAS (HNAS). We are also implementing an archive solution with the new NAS that will archive files that haven't been accessed in X amount of time. I can't seem to find a way to replicate the data w/o changing the access times on the destination copy. I've tried rsync and cpio and both end up modifying the destination copy's access time. I've even tried reading the source from a read-only snapshot. So far the only way I can get these files on the new NAS w/o updated access times is using netbackup/NDMP but the volume of data is far to great for this approach. I'm wanting to use rsync or some other tool that has incremental capabilities so I can start moving the data online w/o downtime, and then take a small outage to do a final sync and then cutover. Anyone have any suggestions? I have linux and solaris hosts at my disposal. So far the behavior has been the same from Solaris 10 and RHEL 5 clients.
