Best Kopia alternatives on desktop in 2026
Kopia earns its fans by pairing content-addressable snapshots and end-to-end encryption with an actual GUI, so the same tool works for a homelab and a laptop. It is the tool an XDA writer credited with replacing a year of backup scripts. Still, Kopia is not the right pick for everyone. Some teams need a CLI-only footprint, some want a paid product with support, and some want a UI polished enough to hand to a non-technical family member. These seven Kopia alternatives cover those needs across Windows, macOS, and Linux.
Every pick handles deduplication, encryption, and multiple storage backends. Prices reflect published pricing pages; open-source picks are noted as such.

Why people leave Kopia
- Kopia’s GUI is more comfortable than the average open-source tool, but the split between the Kopia CLI and the Kopia UI still leaves seams that server admins notice. Some deployments want CLI-only.
- Kopia repositories are content-addressed, which is great for dedup and terrible when you need to relocate a repository between clouds. Restic and Borg handle repository moves the same way, but Duplicacy and Arq feel simpler for that specific job.
- Documentation is community-owned and thin in places. Users on Reddit’s
/r/selfhostedregularly ask for the same “how do I schedule this” questions the docs do not answer clearly. - There is no paid support tier. If a repository throws an error at 2 a.m., you post on GitHub or the forum and hope.
- Newer commercial products ship niceties Kopia does not: proactive integrity checks, native S3 Object Lock support with a UI toggle, and mobile push notifications.
The alternatives
Restic, best for CLI teams that never open a GUI
Restic is the reference command-line backup for a reason. It runs identically on Linux, macOS, and Windows, encrypts everything client-side, and its dedup engine keeps repositories small without demanding heavy RAM. Cron and systemd timers cover scheduling; nothing else is needed.
Where it falls short: no GUI, no built-in web dashboard. If your team wants dashboards, you either use restic-browser or wire Restic into Grafana yourself.
Pricing:
- Free: fully free, BSD-licensed
- Paid: no paid tier
- vs Kopia: comparable capability at a smaller mental model, minus the GUI
Migrating from Kopia: no direct importer, but the model maps cleanly (snapshots, tags, hosts). Rerun your first full backup into a fresh Restic repository and copy schedules from your Kopia cron.
Bottom line: the pick if you never miss a GUI and want a single binary that just works.
BorgBackup, best for Linux-first pipelines
Borg is CLI-only, deduplicates more aggressively than most tools, and pairs beautifully with Borgmatic for scheduling and BorgBase for managed hosting. It is the default backup engine for a large chunk of self-hosted Linux users.
Where it falls short: Borg requires the Borg binary on the storage host too, which limits generic S3 and B2 use unless you tunnel via rclone. Windows support is experimental.
Pricing:
- Free: fully free, BSD-licensed
- Paid: BorgBase managed hosting from $2/month, 10 GB free
- vs Kopia: better dedup ratios in most cases, but no client GUI
Migrating from Kopia: create a new Borg repository and run a full backup. Use Borgmatic to translate Kopia’s schedule policies into YAML.
Bottom line: best deduplication on Linux, at the cost of a Linux-shaped mental model.
Duplicati, best for Windows users who want a web UI
Duplicati 2.1 landed in 2025 and finally fixed most of the historical database corruption complaints, and the browser-based UI remains the most approachable free option. Schedule jobs from a web dashboard, target Backblaze B2, S3, WebDAV, or almost anything else.
Where it falls short: the project has a reputation for restore-time surprises. Test restores every quarter, not annually.
Pricing:
- Free: fully free, LGPL-licensed
- Paid: no paid tier
- vs Kopia: friendlier setup for non-CLI users, less battle-tested than Restic or Borg
Migrating from Kopia: create a new Duplicati job pointing at the same destination. Duplicati’s schedule interface is friendlier than Kopia’s, so plan the job cadence upfront.
Bottom line: the right first pick for Windows users who want dashboards and are willing to test restores religiously.
Duplicacy, best for multi-machine repositories
Duplicacy’s lock-free deduplication design lets multiple clients back up to one repository without stepping on each other, which is the specific problem Kopia and Restic solve less elegantly. Its Web UI is competent, and command-line control is available for scripters.
Where it falls short: the personal license is $22/year and the commercial license runs higher, so this is not the free pick.
Pricing:
- Free: 30-day trial
- Paid: $22/year personal, $75/year commercial
- vs Kopia: paid but the multi-machine story is genuinely cleaner
Migrating from Kopia: kick off a fresh full backup per client into a shared repository. Duplicacy will dedup common data automatically.
Bottom line: the pick for homelabs backing up multiple machines to one destination.
Arq Backup, best for macOS-first buyers who want support
Arq is the polished paid option on Mac and Windows. It has a real installer, a UI written to look native on each OS, and email support that answers. Storage backends include the usual suspects, plus Arq Cloud if you want to buy storage from them too.
Where it falls short: no Linux support and no free tier past the trial.
Pricing:
- Free: 30-day trial
- Paid: $49.99 one-time for Arq 7 personal, $59.99/user for Arq Premium
- vs Kopia: expensive by comparison but delivers real support and polish
Migrating from Kopia: point Arq at the same source folders and let it build a fresh repository. Do not mix Kopia and Arq snapshots in one bucket.

Bottom line: the pick for buyers who want a company on the other end of the email.
rclone, best for cloud transfer plus optional backup
rclone is not a dedicated backup tool, but its rclone sync, rclone copy, and rclone crypt primitives are enough to build a solid backup pipeline. It talks to 70+ cloud backends and has been packaged into thousands of backup scripts.
Where it falls short: no snapshotting, no incremental history without pairing with Restic or Borg.
Pricing:
- Free: fully free, MIT-licensed
- Paid: no paid tier
- vs Kopia: not a real substitute alone; combined with Restic or Borg, better cloud reach than Kopia
Migrating from Kopia: point rclone at a Kopia snapshot mount and copy it into cloud storage as flat objects. Better: pair rclone with Restic and treat rclone as the transport layer.
Bottom line: essential glue in most homelabs; not a Kopia replacement on its own.
Veeam Agent, best for Windows PC image backups
Veeam Agent for Microsoft Windows is a free personal-use tool that does bare-metal image backup with a native installer, plus scheduled file-level jobs. Everything an SMB Windows shop expects, without the Veeam data center license.
Where it falls short: Windows and Linux only, no macOS, and the free tier caps some features (no direct S3-compatible target, for example).
Pricing:
- Free: fully free for personal use
- Paid: workstation edition starts around $69 per year per PC
- vs Kopia: not open source, but ships image and bare-metal restore that Kopia does not
Migrating from Kopia: Veeam Agent creates full image backups from scratch. Retire the Kopia repository once you have verified a bare-metal restore.
Download: Website
Bottom line: the pick when you need a full Windows disk image, not a file-level snapshot.
How to choose
Stay on Kopia if the GUI is the reason you like it and the encryption model matches your compliance story. Kopia’s daily-driver strength is that it splits the difference between Restic’s CLI power and a friendly web UI.
Pick Restic if you script everything and never want a GUI. Pick BorgBackup if you are Linux-only and want the strongest deduplication ratios in the field. Pick Duplicati if you are on Windows, want a web dashboard, and are willing to test restores quarterly.
Pick Duplicacy when you back up several machines to one repository and can spend $22 a year on personal licenses. Pick Arq Backup when you want a paid product with support on Mac or Windows. Add rclone as glue when you need broad cloud backend coverage; do not treat it as a standalone backup. Reach for Veeam Agent when the actual requirement is a bootable Windows image, not a file-level snapshot.
