Related Restic is the best choice for most people — broad cloud backend support, strong deduplication, and the largest community. BorgBackup wins if storage efficiency is your top priority (best-in-class compression). Kopia is the best pick if you want a web UI or need a centralized repository server. All three are open-source, deduplicated, encrypted backup tools. They solve the same core problem — creating reliable, space-efficient backups — but differ in philosophy, features, and ecosystem. This is the biggest differentiator. If you want to back up to cloud storage, Restic and Kopia pull far ahead. BorgBackup limitation: Borg only supports local and SSH-based repositories natively. Backing up to S3 or B2 requires mounting via rclone or using BorgBase (managed hosting). This is by design — Borg optimizes for direct repository access. Performance depends heavily on data characteristics, but general patterns: Key insight: BorgBackup typically achieves 10-30% smaller repositories than Restic for the same data, thanks to its superior compression. Kopia falls between them, with zstd compression closing the gap against Borg. Restic and BorgBackup both need external scheduling. Borgmatic wraps BorgBackup with YAML-based configuration, scheduling, and monitoring hooks — making Borg much easier to automate. For a self-hosting setup backing up to Backblaze B2 or S3, Restic is the default recommendation. For local NAS backups where storage cost matters, BorgBackup with Borgmatic. For those who want the easiest experience with a visual interface, Kopia. No — each tool uses an incompatible repository format. Switching requires restoring data from the old tool and creating a new backup with the new tool. There is no direct migration path between any of these three. Plan for this by keeping the old repository accessible until you've verified the new backup is complete. Restic has the most mature B2 integration. It supports B2 natively as a backend and handles large uploads efficiently with chunked transfers. Kopia also supports B2 well. BorgBackup does not support B2 directly — you need to mount B2 as a filesystem using rclone or use a network storage layer, which adds complexity and can reduce performance. Yes, all three can back up Docker volumes. The approach is the same: stop the container (or use a database dump for databases), then back up the volume directory on the host. Borgmatic and Kopia's built-in scheduling make this easier to automate. Restic requires a wrapper script or cron job to handle the stop/backup/start sequence. Restic and Kopia support Windows natively with official binaries. BorgBackup does not have official Windows support — it runs on Linux and macOS only. If you need to back up Windows machines, Restic or Kopia are your options. For mixed environments, Restic is the safest choice due to its broader platform support. BorgBackup is typically fastest for local backups due to its efficient deduplication and compression pipeline. For cloud backups, Restic and Kopia perform similarly — both parallelize uploads and handle large repositories well. The bottleneck for cloud backups is usually network bandwidth, not the tool itself. All three handle multi-terabyte repositories without issues. Kopia has a built-in web UI showing backup status, schedules, and repository health. Restic and BorgBackup are CLI-only — you need external monitoring. A common approach is using Healthchecks or Uptime Kuma to monitor whether backup scripts complete on schedule. Borgmatic (the BorgBackup wrapper) supports Healthchecks pings natively.
