SuperDuper! is a long running Mac backup app from Shirt Pocket. It makes a full copy of your drive on another disk. If your main drive fails or an update goes wrong, you can start up from the copy and carry on. Version 4 brings a fresh interface and a much faster Smart Update, so keeping that clone current takes very little time after the first full backup.

Key Features

  • Creates bootable clones you can start your Mac from in an emergency
  • Smart Update copies only the files that changed since the last run
  • Scheduling runs your backups automatically at times you choose
  • Scripts can run before and after a copy for custom workflows
  • Clear logs show exactly what was copied and report any problems

How to Download

  1. Download from the official site to get the current version.
  2. Open the download and drag SuperDuper! into your Applications folder.
  3. Connect a backup drive, pick your source and destination, and run your first clone.

System Requirements

The current SuperDuper! 4 line needs macOS 14 or later, on Intel or Apple Silicon, according to Shirt Pocket. Your destination drive needs at least as much space as the data you plan to copy onto it.

FAQs

Is a clone the same as a regular backup?

A clone is an exact copy of your drive. That means you can boot from it and work right away, which a plain file backup cannot offer.

How often should I update my clone?

Many people run Smart Update daily or weekly. Because it only copies changes, regular runs are quick and keep your safety net close to current.

Does SuperDuper! cost money?

Basic copying is free, and a paid registration unlocks scheduling, Smart Update and other advanced features. The official site lists what each option includes.
