There is a backup engine in the tree — it splits files into chunks, encrypts them before they leave your machine and can put them back. None of it is switched on in a shipping install yet, and mounting OneDrive, S3 or a bucket as a folder is not written at all. So this page tells you what is real and nothing else.
Coming soon
None yet, and pretending otherwise is how the last version of this site lost people's trust. Here is what is being built instead.
Split, uploaded piece by piece, resumable.

Restore from the catalogue of what was uploaded.
One add-on in four bundles is deliberate — the personas genuinely overlap, and holding it twice is never charged twice.
An add-on is not sold on its own — a bundle is, and holding the same add-on through two bundles is never charged twice. See the bundles.
A fresh install hides anything below the default bar on this add-on’s Minimum readiness slider in Settings › Features. These are in the app today.
Download File Manager, then pick the bundle that grants it.
