6 TB internal Time Machine Backup Advice
apologies for the multiple posts today. i am trying to finalize my backup on a new system.
i have previously run an OS drive and another "data drive" in my mac pro while having the other two drives act as daily clones.
however i am having a hard time finding a reasonably priced external drive to back up my 4 TB data drive (it will give me a lot of years to add to it).
so i am considering buying a 6 TB WD "Red" drive and putting this in the machine and using this INTERNAL drive to act as a backup for the 4 TB data drive.
if i do this i can repurpose the 4TB drive that is currently acting as a clone for the OS drive.
if i do this i will have internal drives acting as time machine backups and i can buy a more reasonably priced 4 TB external drive to act as a daily clone for the OS drive.
is this a good or bad idea?
THANKS for any help as i try and finalize this.
Mac Pro, OS X Yosemite (10.10.1)
