Unbacked watches your dev folders and excludes rebuildable caches from Time Machine (node_modules, .next, DerivedData, build/). Back up less data, use less storage, and reduce upload for cloud/remote backups.
A clear view of what's excluded and how much space you're not backing up
Keeps exclusions up to date as caches appear.
See excluded folders and estimated backup data skipped.
Targets rebuildable dev caches. You choose watched folders, and every exclusion is visible and reversible.
Uses Time Machine exclusions. Runs locally on your Mac.
Development caches pile up fast: node_modules, build artifacts, package caches, .next, DerivedData, and more.
Time Machine spends time scanning and copying data you can regenerate. Backups take longer, backup disks fill faster, and cloud/remote backups upload more than they need to.
Exclusions should be automatic, visible, and reversible. Unbacked detects rebuildable junk and keeps it out of your backups — so Time Machine focuses on what matters.
Smart detection across all major development tools and frameworks
Rapidly finds rebuildable caches in your dev folders.
Continuously scans for new build artifacts and updates Time Machine exclusions.
