Backup

Duplicati14.4k★

Duplicati is the backup tool for people who want a web UI, cloud storage support, and strong encryption without touching a terminal. It backs up to S3, Backblaze B2, Google Drive, OneDrive, and dozens more — all with AES-256 encryption and deduplication. For non-technical users or Windows-first setups, nothing else comes close in accessibility. If you need encrypted backups to cloud storage and want to configure everything through a browser, Duplicati is your best option. Restic is the CLI-first alternative that's faster and more reliable — the self-hosting community trusts it deeply. BorgBackup (with Borgmatic) is the performance king for deduplication but only writes to local/SSH paths. Kopia is the newer option gaining momentum. The catch: Duplicati has a reputation problem. Forum threads describe database corruption, failed restores, and poor performance on large repositories. The project has been in "beta" for years. If your backups matter — and they should — test restores regularly. Many experienced admins use Restic or Borg specifically because they've been burned by Duplicati.

BorgBackup13.1k★

BorgBackup is the backup tool you pick when every byte of storage costs money. It delivers best-in-class deduplication and compression, squeezing backups roughly 10% smaller than Restic with the same Zstandard settings. If you're running a homelab or VPS with limited disk, that adds up fast. Restic is the main rival — faster at creating backups and natively supports S3, which Borg doesn't without rclone bolted on. Kopia is the newer contender with a GUI and parallel cloud uploads. For commercial, Backblaze B2 with any of these works, but there's no SaaS worth paying for when OSS is this good. Use Borg if you back up to local or SSH targets and care about storage efficiency. It also sips less RAM than Restic — a real win on cheap VPS instances. The catch: no native Windows support and no built-in cloud storage. If you need S3 or cross-platform, Restic is the easier path.
