Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 73 of the 91 other file storage and sync services we grade
Duplicati backs up files from desktops, servers and NAS devices to storage you pick, such as S3, Azure Blob, Backblaze B2, OneDrive, SFTP or WebDAV. Data is encrypted on the device before upload. A paid web console adds monitoring, alerts and remote management across many machines.
To get you started, here are 9 things to know about Duplicati, taken from its own pages and our grades.
You set up each backup job and destination, with no store rating on record.
- 1
Best for free backup to your own storage
Duplicati is a free open-source backup client that encrypts before it uploads to storage you choose, with a paid console for watching many machines.
- 2
Paid plans start at $2 a month
As its pricing page puts it: $2 per machine / month, billed annually ($2.50 billed monthly).
- 3
There is a free plan
Console Free plan: insights dashboard, monitoring for up to 2 machines and the last 200 backups.
- 4
It runs on 4 platforms
Web, macOS, Windows and Linux.
- 5
Bring your own storage
Back up to S3, Azure Blob Storage, Google Cloud, Backblaze B2, Dropbox, OneDrive, Box, SFTP, WebDAV or local disks.
- 6
Encryption before upload
Data is encrypted on the device before it leaves, and the vendor says only the customer holds the keys.
- 7
Changed-block uploads
Only changed blocks are sent, which cuts bandwidth use, and retention rules decide how long old versions are kept.
- 8
A 2.8 GPA, above 73 of 91
That is against the other file storage and sync services we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
The plain part of Duplicati you could make: reports. What surrounds it you could not. The 4 things listed below take a company, not a weekend.

The report card
Best for free backup to your own storage
Duplicati is a free open-source backup client that encrypts before it uploads to storage you choose, with a paid console for watching many machines. Storage is not included, the free console monitors just 2 machines, and alerts and remote management need Pro.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The client is free to download and run, and Pro monitoring is $2 per machine a month billed yearly, under the category's $2.85 line. Storage costs are yours. |
| Free plan and trial | B | The client and a console plan for 2 machines and the last 200 backups are free. One person could live on that, though alerts need Pro. |
| Features | C | Backup with encryption, changed-block uploads and a central console does the job, which is narrower than storage. M365 and Google backup is priced on its own and the console features are gated. |
| Ease of use | C | You set up each backup job and destination, with no store rating on record. |
| Platforms and integrations | B | Web interface plus Mac, Windows and Linux, and many destinations such as S3, Azure, Dropbox, OneDrive and Backblaze B2. No phone apps. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Duplicati is for
- Fits if you want a free backup client and your own pick of storage
- Works for IT teams watching backups on many machines in one console
Who it is not for
- Tight if you run more than 2 machines, because the free console stops at 2
- Not for you if you want alerts for missed backups or remote management, as those need Pro
- Skip it if you want storage included, since self-managed use brings your own
- Watch out: Microsoft 365 and Google Workspace backup is $0.50 self-hosted or $1.50 managed per user a month, and Enterprise starts at 10 machines
Good to know
Good for
- People who want a free backup client and their own choice of storage

Worth knowing

- Enterprise starts at 10 machines on a yearly contract and is sold through sales.
- Storage is not included on the self-managed route; extra integrated storage is $0.60 per additional 100 GB per month, billed yearly.
- Microsoft 365 and Google Workspace backup is priced separately: $0.50 per user / month self-hosted, $1.50 managed, both billed yearly.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Duplicati you could make: reports. What surrounds it you could not. The 4 things listed below take a company, not a weekend.
It is one of the better ones too: its GPA of 2.8 is higher than 73 of the 91 other file storage and sync services we grade. It costs $24 a year. Duplicati is open source, so there is a third way: take its code and run it yourself.
What you could make
- Reports: an app builder makes this well.
What you could not
- Apps for macOS, Windows and Linux that stay in step with each other.
- It plugs into other products, Amazon S3, Azure Blob Storage and Google Cloud among them.
- End-to-end encryption done properly.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Duplicati’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
