I am using a single external 1TGB USB drive as a secondary backup system for my SBS2008 server.  I have set it to backup the 360GB mirrored  'C' drive each day. The data drive is another mirror pair being backed up by other methods. Will the USB drive eventually fill up or does it just overwrite the changed blocks thus meaning I can connect & not worry about drive filling up. (users data will be on the other drive)

Interesting question.
You probably already saw this link:

At the backup time, there are written only changed blocks. And the older blocks are retained with metadata.
So theoreticly you should run out of place sooner or later. I did not noticed anywhere an option to set for how long the old data is kept. So I PRESUME that backup has some sort of mechanism, that when the backup disk runs out of space, that the oldest blocks are overwritten.
As you have backup disk big enough (2,5 times of size of backed up data), you will need quite some time to figure that out ;)

Well I found out this:

It is almost the same article, but look at the end at Q&A - you don't need to worry about filling up the disk.
