when i first built my nas i configured it as a single volume taking up all my disk space (maybe a noob move), but now i would like to split into a few volumes by the tasks they support - - this will require me to delete the volume ... so i would like to connect an external drive and back up my files and start my installation fresh .. but i already have active backup for business backing up to this single volume - so my question is, what files do i need to make sure i copy to the external HD (the active backup for business backup files) and how do i get active backup to recognize them in their new location once i have restored them to an alternate volume
