Backing up data to the same drive is just idiocy to start with.
I'd say it is more like 4/5 Idiocy. If the drive gets damaged (or is stolen) then you are out of luck. However, backups to other parts of the same drive do provide redundancy against file corruption or sector damage.
I'm so glad someone else thought that. Backing up data to the same drive is just idiocy to start with. Let alone the issues of having your backup in the same location, (the laptop itself).
There's more than one level of backups. For example, keeping filesystem snapshots or multiple versions of a file helps with accidental deletions or local file corruption. Especially if they (snaps) happen often enough. These can be on the same disk, or on a separate disk.
Then there's recovery (what most people consider "backups") that allow you restore files if your entire harddrive dies.
Obviously, you don't want the latter stored on the same drive. But there's nothing wrong with the former being on the same drive.

"I need to back up part of my hard drive to another part of my hard drive. Just in case my hard drive fails. It's also fine if someone steals my laptop because i back everything up."
