# What happens if a backup is interrupted?

Nothing is lost. If a backup stops partway — you quit the app, the Mac sleeps, the network drops — it continues from where it left off next time and never re-uploads anything it has already saved.

If Storage Studio closed while a backup was running, the card says so — for example *"The last backup didn't finish — Storage Studio closed while it was running. It picks up where it left off, so nothing is lost."* Press **Back up now** to carry on immediately, or let it resume on its own.
