Frequently asked questions
Does DittoBot require an account?
No. There's nothing to sign up for. Open the app, add a network drive and a folder, and it starts mirroring — no login, ever.
What does it back up to?
Any SMB network share — a NAS, another Mac or PC acting as a file server, a rack-mounted server, whatever you already have on your network. DittoBot doesn't provide cloud storage of its own; it mirrors to hardware you control.
Can it back up a remote Linux server, not just my Mac?
Yes. Add a connection under Source Servers with a password or a private key (passphrase-protected keys are supported), then pick specific folders on that machine to mirror — same destination assignment, versioning, and exclude-pattern handling as local folders. One thing worth knowing: FSEvents can't watch a remote host, so SSH-sourced folders sync on the periodic safety-net pass rather than near-instantly on every change.
How is this different from Time Machine?
Time Machine snapshots your whole disk to one designated backup volume. DittoBot mirrors specific folders you choose — continuously, in real time — to one or more SMB destinations at once, with per-folder versioning, exclude patterns, and a bandwidth throttle. The two aren't mutually exclusive; plenty of people run both.
Is my data private?
Yes. Files move directly between the machines you configure — your Mac, an optional SSH source, and the destination — over your own network. There's no cloud service, no account, and no analytics in between. See the Privacy Policy for the full details.
What happens if a drive disconnects mid-backup?
DittoBot detects the disconnect and reconnects automatically, with exponential backoff and jitter, and also re-checks whenever your Mac wakes from sleep. Nothing needs to be manually restarted.
Can one folder back up to more than one destination?
Yes — assign a folder to any number of configured network drives. It backs up to each one sequentially (never in parallel), so it never contends with itself for bandwidth.
Why isn't this on the Mac App Store?
DittoBot needs raw filesystem access, SMB mounting, and background file-system event monitoring — none of which the App Sandbox allows. It's signed and notarized directly with Apple using a Developer ID certificate and distributed as a direct download instead.
Is DittoBot free?
Pricing details will be available once DittoBot officially launches.
What does it require?
A Mac running macOS 14 or later.
