Iomega says it might add this feature later via a firmware update. The StorCenter ix2 supplies many popular NAS features save one: remote access via the Web. Other than the content of My Documents and Desktop folders, you can't choose to back up any other folders on the hard drive unless you choose to back the entire hard drive altogether.
The software, though easy to use, is very limited. The StorCenter ix2 comes with EMC Retrospect Express HD backup software.
