Kopia

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview

Kopia is a fast and secure open source backup and restore tool. It creates encrypted, compressed and deduplicated snapshots of your files and directories and stores them in a repository that can live on a filesystem, on cloud object storage or on a Kopia repository server. This image delivers Kopia fully installed and configured in server mode with its browser based web UI, so a production grade backup server is running within minutes of launch.

Application Stack

The Kopia static binary installed under /opt/kopia and run by a dedicated unprivileged service account in server mode. A demo filesystem repository, the Kopia config and the content cache stored on a dedicated data disk so they are independently resizable and survive instance replacement. A systemd service that starts the Kopia server on boot and restarts it on failure. An nginx reverse proxy that publishes the web UI on port 80 with WebSocket support for live task updates.

Backup and Restore

Kopia takes incremental snapshots that are encrypted client side with strong cryptography, compressed and globally deduplicated, so repeated backups are fast and storage efficient. Define sources and policies in the web UI or with the command line, schedule snapshots, browse and mount past snapshots, and restore individual files or whole directories. Repositories can be hosted on a filesystem, on Amazon S3 and other object stores, or on a Kopia repository server.

Secure First Boot

On the first boot of your instance a one shot service generates a fresh web UI password, a fresh server control password and a fresh repository password, all unique to that instance, recreates the demo filesystem repository and writes the passwords to a root only file. The Kopia server binds to loopback only and is never exposed without authentication. No shared or default credentials ship in the image.

Ready To Use

The web UI is served on port 80 through nginx. Sign in with the generated credentials to connect repositories, define sources and policies, run and schedule snapshots, and restore data. The same server can act as a repository server for other Kopia clients on your network.
