Browser-driven encrypted backups to nearly any storage target, with more knobs than charm.
licenseMIT
runson your machine
installSigned Windows/macOS/Linux package or Docker container, then configure backups through its local web UI
dataEach backup target contains encrypted compressed `.dblock` data volumes, `.dindex` indexes, and one `.dlist` manifest per version; a local database accelerates catalog and restore operations.
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.
setupThe 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.

Encrypted snapshots to storage you choose; the cloud bill and restore drills are still yours.
licenseApache-2.0
runson your machine
installInstall KopiaUI or the CLI from native Windows/macOS/Linux packages, then create or connect to a repository
dataSnapshots 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.
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.
setupYou 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.

Restic with buttons, schedules, checks, and enough guardrails to avoid living in a terminal.
licenseGPL-3.0
runsyour server
installStandalone installer or Homebrew on macOS/Linux, Windows installer, or Docker Compose; it downloads/manages restic on first run
dataBackups 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.
the catch vs Dropbox PlusIt creates versioned backups, not Dropbox's live bidirectional folder sync, sharing links, collaboration, and seamless access from every device.
setupYou still have to choose and provision storage, protect the repository password, grant filesystem access, and test restores; macOS may require Full Disk Access.

resticExcellent backup engine; still a terminal, scheduler, and retention policy you must assemble yourself.
SyncthingExcellent folder replication with versions; no object-store backup, restore testing, or share-link layer.

why people still pay for Dropbox Plus
People still pay for Dropbox Plus because storage subscriptions sell confidence that files will still exist after a lost device, bad sync, or provider incident. The recurring cost buys chunking, encryption, conflict detection, versions, garbage collection, bandwidth, restore drills, monitoring, billing, and disaster recovery, not just the visible interface. If none of that applies to you, any pick above saves $143.88 a year.
