Keeping a USB drive in sync with a NAS - can I do this?

[ptdimarzio]

Thanks Dave. I wonder if I'm using the right terminology (I'm not all the fluent with Mac drives and disks) ...

Buffalo calls the partitions "shared folders". I have shared folders established for archives, backups, etc. One of these is called "Lightroom Backup". A utility called NASNavigator lets me mount any shared folder I want and it appears in finder as a disk image. So basically I open NASNavigator, click on the Lightroom Backup shared folder, and a disk icon appears called Lightroom Backup. I can then open this disk and manipulate the files as I wish.

So basically I see my USB-attached disk Lightroom, and my NAS disk Lightroom Backup, as disk icons and I copy files between them.

I did just open SuperDuper! with the Lightroom Backup drive mounted and it isn't showing up in the list of drives so I guess I'm out of luck.
