You're right that storage level snapshots are filesystem agnostic. I'm not sure 
why you believe you won't be able to restore individual files by using a NetApp 
snapshot? In the case of ZFS you'd take a periodic snapshot and use it to 
restore files, in the case of NetApp you can do the same (of course you've to 
have the additional step to mount the new snapshot volume.) Is this convenience 
tipping the scales for you to pursue ZFS?

Yes, we'd run out of LUNs.  We're talking about two weeks of daily
snapshots on six filesystems.  Each snapshot on the Netapp would
become a separate iSCSI LUN.  They need to be mounted on the server so
that our admins can locate and restore missing files when necessary.
