How much disk space do I require

[Thestarfishkid]

I want to add an external hard drive to my NAS for use for Hyper Backup.
I have a total of 12Tb of data on my disks. If I wish to hyper backup all the data do I need at least a 12tb hard drive?

If your total data size is 12TB, then yes.

Unless... you are expecting to do this regularly and retain versions, in which case you need >12TB.
