Terra byte drives are quite cheap now.

A hard drive attached to your system is not a backup. It's online
local storage. The two are not the same thing. IMO, an ideal backup
system should be

A) read-only (so a mistake, malware, or hardware error can't delete or
corrupt it)
B) physically distant (so fire, flood, etc. won't take it out at the
same time as your main copy)
C) immediately available
D) incrementally expandable
E) long-lived
F) cheap

Some of these conditions are somewhat mutually incompatible, but
that's the problem with ideals. Again IMO, external media satisfy
conditions A, B, and D. A hard drive attached to your system satisfies
C; if you only attach it to your system when you're actually backing up
or restoring, it satisfies A only as long as it doesn't satisfy C. I
don't trust just about anything to satisfy E, unfortunately...
