Ernie, I keep separate disk (also 1TB) and 2 backups. My Time Machine is strictly for the MacMini but I could instruct it to backup also the other drive. I decided it might be not optimal since I prefer to have backup disk unpowered and disconnected to avoid problems (lightning, virus, mechanical wear etc). I still turn on Time Machine disk only for the backup but I have the option on using it all the time when I work on something without backup being exposed. I use Carbon Copy for backups.
I've read somewhere that Time Machine backup drive should not have any other files because it is not doing proper job (deleting old files) when disk is full. It sounds like software bug and might be corrected by now. As for the folders - it should not matter how deep it is as long as you can point to this directory.
