Edge is the 3to1go app that makes backups. Run one Edge on every machine whose files you want to protect. Each Edge works on its own and only needs to reach Central to upload.

​
What Edge does

  • Finds backup jobs by scanning for folders that contain a .upload_dir marker.
  • Detects changes with a path-and-size fingerprint, so unchanged folders aren’t uploaded again.
  • Builds and encrypts archives as tar.zst files. The key stays on Edge unless you copy it for safekeeping or browser-based downloads; it is never sent to Central’s server.
  • Uploads to Central in chunks, resuming and retrying when the connection drops.
  • Runs on a schedule you set with a cron expression, weekly by default.
  • Restores snapshots from Central back into the original folder.
  • Sends notifications to ntfy and runs your own scripts around each job.

​
Folders it uses

Back up Edge’s config folder, especially encryption.key. Without that key, this Edge’s snapshots cannot be decrypted. See Encryption key.

The Edge UI

Open http://<edge-host>:6556/. The main page shows:
  • Selected Jobs: each backup job, its last state, the size of its last backup, and buttons to browse files, force an upload, restore, or edit it.
  • Directories Under Scan Root: a folder browser for choosing what to back up. Turn on Show hidden to see hidden folders.
