Bareos vs Kopia

Bareos is backup software for computers and servers, with mixed backup scope and restore modes. It includes ransomware protection and supports Linux, macOS, Windows, web, and self-hosted environments. The Community plan is open source, requires no subscription, and provides access to the public repository and complete source code at free. The paid Subscription plan starts at €480 a year and has a minimum of 10 units. Bareos is made by Bareos, founded in 2012 and headquartered in Cologne, Germany. The combination of computer and server backup can suit environments where both kinds of systems need protection. Its listed platform range includes desktop operating systems and web access, while self-hosted use is also supported. Buyers can choose the free Community edition or a paid annual subscription, whose stated minimum is 10 units.

Kopia is an open-source backup and restore tool that creates encrypted snapshots of selected files and directories. Snapshots are incremental, and content deduplication stores duplicate file content only once in a repository. Policies can schedule snapshots, set exclusions, define retention, and apply compression. Recovery options include mounting a snapshot as a local disk, restoring an entire snapshot to a chosen location, or selecting individual files. Kopia encrypts data and filenames before they leave the machine, supporting AES-256 and ChaCha20. Storage can use Amazon S3 and compatible services, Azure Blob Storage, Backblaze B2, Google Cloud Storage, WebDAV, SFTP, local or network storage, and some Rclone providers; Rclone support is experimental. Reed-Solomon error correction and repository consistency checks address data integrity. CLI and GUI interfaces are available, with optional server mode and an API for managing multiple machines. KopiaUI provides a web application in server mode. The software is free, but storage must be provisioned and paid for separately.
