I'm running 13TB on my Mac Pro with a standard 2TB boot drive, and 3+4+4 the fourth being a Time Machine Backup drive. It can hold some things, but isn't nearly large enough to hold all of my data (currently using 8TB between the first 3 storage drives). What is the best way to back all of this data up preferably using Time Machine? I'm already excluding lots of stuff to get my key items to fit on the 4TB, but have been bad about making regular backups because of the storage rapidly running out. Can 12TB external RAID configs be read as a single drive? Or can anybody point me how to back up data using Time Machine spread over more than one drive if it is possible. Just wondering how to approach this, feel free to recommend any equipment that comes to mind. THANK YOU!
