The UUID of a Linux partition is the Universally Unique IDentifier of that partition. I would say with a fair bit of confidence that in this and most scenarios, the Linux partition UUID has more of a local machine scope.
Cloning a hard drive can be useful for backing up (byte for byte) or moving data to a new hard drive. In Ubuntu this is pretty simple, though it is important to pay attention!
We’re going to use a few tools:
- fdisk to create the partition
- mkfs to create the filesystem
- dd to clone bytes
