Every connection starts at the endpoint, never at the server, so Borg Backup Server can back up Linux, Mac, and Windows machines behind NAT and firewalls without opening a single inbound port. A lightweight agent on each machine polls for tasks over HTTPS, pushes deduplicated archives over SSH, and reports live progress. Append-only SSH access means an endpoint can add and restore archives but never prune or delete them. The dashboard shows backup charts, server stats, and active jobs at a glance. Plans run from hourly to monthly, several per client, built from reusable directory templates for common server roles, with per-plan retention from hourly to yearly. Lost a file? Browse the archive tree in your browser, tick what you need, and restore it to the client or download a .tar.gz. MySQL and PostgreSQL dumps run before each backup and restore as a copy or a replacement. Repositories can live on the server, on BorgBase, Hetzner, or rsync.net, and mirror to S3-compatible storage such as AWS, Wasabi, or Backblaze B2. Apprise alerts reach more than 100 services, and a nightly report lands in your inbox. Two-factor login and role-based access guard the console. Upgrades roll out to the server and every agent together, and the server backs itself up daily. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
