Maybe woodworking? It can get dusty and you need some room but you can also make smaller things that don’t need big power tools or a lot of room. Like miniature things.
Or computer programming. Create an app. Or do something fun like follow one of the coding challenges from the YouTube channel The Coding Train
Not what your asking but, I have a backup hard disk at my workplace. I have the same size disk at home and when I need to update something on my backup, I copy it to the at home disk. I bring that to work and bring back the other disk home. This way, there is always a backup away from home. All encrypted so nobody can steal the data.
Other options can be a friend or family member.
And for other stuff I also have it on Google Drive.
