I saved Network Backup for last, because I figured it would probably be the easiest thing to do and I wanted to give myself a break at the end. But things turned out differently.
Network backups are managed via the Backup and Restore Center in the Control Panel. Unlike other places in Vista (*cough* Network and Sharing Center *cough*), you can actually back up and restore directly on the Backup and Restore Center's main screen in simple mode!
Standard backup and restore is pretty cut and dry: You click on "Back up Files," it asks you where you would like to back up your files and what drives you would like backed up, and then you're off to the races.
Network Backup works a little more like this. You select "Back up Files" (Figure 7). Windows will stop you yet again for administrative permission.

Browse for the appropriate network location (Figure 8).

And enter your user name and password (Figure 9). Note that I specifically created an account on the remote computer for this purpose.

But then Vista tells you that you don't have Full Control of the folder you are trying to access (Figure 10).

But you do! (Figure 11)
