Alternatives to Kopia

An encrypted snapshot backup tool with both a command line and a proper desktop app, pointed at whatever storage you choose. The listings below can replace it for an important use case. Each note says what changes if you switch.

Replacements

Listings that take over the same core job as Kopia.

  • restic

    A single-executable backup program that makes encrypted, deduplicated snapshots and can send them almost anywhere.

    FreeOpen sourceWindowsmacOSLinuxCommand line

    restic offers similar encrypted deduplicated snapshots as a single command-line binary, but it lacks Kopia's desktop app and per-directory retention policies.

  • BorgBackup

    A deduplicating archiver for Linux, macOS and BSD that makes daily backups cost almost nothing beyond the day’s changes.

    FreeOpen sourceLinuxmacOSCommand line

    BorgBackup provides deduplicated authenticated-encrypted archives over SSH with FUSE mounting, but it is command line only and lacks a native Windows build.

  • Duplicati

    A backup client with a web interface that encrypts your files and pushes them to more than twenty cloud services.

    FreeOpen sourceWindowsmacOSLinux

    Duplicati uses a web interface and scheduler for encrypted incremental backups to many cloud services under MIT, though large restores can be slow.

  • Duplicacy

    A deduplicating cloud backup tool whose lock-free design lets several machines share one storage bucket.

    FreemiumProprietaryWindowsmacOSLinux

    Duplicacy lets several machines share one deduplicated cloud bucket without a server, but its licence is not open source and the GUI is paid.

  • Backrest

    Schedule and restore restic backups through a browser interface.

    FreeOpen sourceWindowsmacOSLinuxSelf-hosted

    Backrest adds a browser interface for scheduling and restoring restic backups, so you move to restic's repository format under GPL-3.0.

    A desktop front end for BorgBackup, so encrypted deduplicated backups stop being a cron job.

    FreeOpen sourcemacOSLinux

    Vorta is a desktop front end for BorgBackup on macOS and Linux with profiles and archive browsing, but has no Windows support.

  • Arq

    Encrypted backup software for Mac and Windows that stores backups in your own cloud account or disk.

    PaidProprietaryWindowsmacOS

    Arq is paid, closed-source snapshot backup for Mac and Windows with end-to-end encryption to your own storage, and has no Linux version.

  • rustic

    Create encrypted, deduplicated backups in restic-compatible repositories.

    FreeOpen sourceWindowsmacOSLinux

    rustic writes encrypted deduplicated backups in restic-compatible repositories, though it is younger than restic and compatibility should be checked.
