Sync Disk

Your files change all day. Your backups shouldn’t have to wait.

Sync Disk is a lightweight macOS app that quietly mirrors your important folders to an external drive, USB storage, or NAS in real time. Every change is tracked, so you can go back and recover an older version whenever you need it. 🛡️

No complicated backup setup. No waiting for a scheduled sync. Just keep working, and Sync Disk takes care of the rest in the background.

What makes it different ✨

1. ⚡ Real time syncing
   Changes are detected instantly and mirrored to your external storage using native macOS file events.

2. 🕐 Complete version history
   Accidentally changed or deleted something? Browse previous versions and restore the one you need.

3. 💾 Save space on your Mac
   Sync Disk can safely remove verified local copies of synced iCloud files, helping free up valuable SSD space.

4. 🔒 Built for reliability
   File history uses content based deduplication and crash resilient journals, so your versions stay organized without relying on SQLite.

5. 🎯 Made for macOS
   A clean Finder inspired interface, menu bar access, folder previews, breadcrumbs, and a simple history timeline make everything feel native.

I built Sync Disk because I wanted something simple: my files should be backed up while I work, not after I remember to back them up. ❤️

If you use external drives for your projects, photos, code, or important files, Sync Disk is made for you.

👉 Keep working. Keep your files safe. Never wonder which version you lost again.
