THE DEVIL SUGGESTS
Build your own NAS
Make a network-attached storage box for files you want available around the house. It is a good excuse to sort out storage before drives become a drawer full of mysteries.

Do it
- Gather a suitable computer, drives and power cables.
- Decide which files the NAS should hold and how much space they need.
- Install a NAS operating system or file-sharing service.
- Create separate folders for shared files and backups.
- Test restoring a file from a backup rather than assuming it works.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
