# What is the "Fast drive working set" in Data Backup?

It's a backup set Storage Studio creates for you that protects its own folder on your fast drive — where your relocated apps and folders live. It does nothing until you give it a destination, so keeping the fast drive safe needs no setup beyond choosing where the backups go.

Pick a destination that **isn't** the fast drive itself — another drive or a cloud account — so a failing fast drive can't take its backup with it. This set can't be deleted, only switched off.
