Duplicati
open sourceMITLocal15kjul 2026Browser-driven encrypted backups to nearly any storage target, with more knobs than charm.
The catch vs Dropbox PlusIt is a backup system rather than a live synced workspace, so instant file propagation, sharing, collaboration, and mobile browsing are the main losses.
Install, platforms & data +
- platforms
- desktopwebone-click install
- install
- Signed Windows/macOS/Linux package or Docker container, then configure backups through its local web UI
- setup
- The first setup is not just an install: you must supply destination credentials, choose encryption and retention, preserve the passphrase, and understand how to rebuild from remote volumes if the local database is lost.
- your data
- Each backup target contains encrypted compressed `.dblock` data volumes, `.dindex` indexes, and one `.dlist` manifest per version; a local database accelerates catalog and restore operations.

Kopia
open sourceApache-2.0Local14kaug 2026Encrypted snapshots to storage you choose; the cloud bill and restore drills are still yours.
The catch vs Dropbox PlusIt protects snapshots well, but it does not provide Dropbox's continuously synced working folder, sharing workflow, collaboration, or consumer cloud experience.
Install, platforms & data +
- platforms
- desktopclione-click install
- install
- Install KopiaUI or the CLI from native Windows/macOS/Linux packages, then create or connect to a repository
- setup
- You must provision and pay for the storage target, enter its credentials, and safeguard the repository password, Kopia cannot recover data if that password is lost.
- your data
- Snapshots live in an encrypted, deduplicated, content-addressed Kopia repository on local/NAS, SFTP, WebDAV, object storage, rclone, or supported cloud targets; small blocks are packed into opaque blobs.

Backrest
open sourceGPL-3.0Self-host7.1kaug 2026Restic with buttons, schedules, checks, and enough guardrails to avoid living in a terminal.
The catch vs Dropbox PlusIt creates versioned backups, not Dropbox's live bidirectional folder sync, sharing links, collaboration, and seamless access from every device.
Install, platforms & data +
- platforms
- desktopwebone-click install
- install
- Standalone installer or Homebrew on macOS/Linux, Windows installer, or Docker Compose; it downloads/manages restic on first run
- setup
- You still have to choose and provision storage, protect the repository password, grant filesystem access, and test restores; macOS may require Full Disk Access.
- your data
- Backups are encrypted, content-addressed restic repositories on the chosen local, SFTP, object-storage, or rclone target; Backrest keeps local JSON configuration, cache, and service data.
