--- title: Duplicati canonical: https://saasranked.com/software/duplicati/ category: Backup Software points: 86 rank: 2 of 9 facts_checked: 2026-10-08 --- # Duplicati Free, open-source backup client that encrypts files before sending them to your own drives, NAS or dozens of cloud services. 86 points out of 100. #2 of 9 backup tools. Vendor: Duplicati Inc. Website: https://duplicati.com/ - The backup client is open source under the MIT licence and free for Windows, macOS and Linux [3]. - Data is encrypted with AES-256 on your PC before it is uploaded [2][3]. - Backups can go to local folders, network storage over SFTP or SMB, Amazon S3, Backblaze B2, OneDrive, Google Drive, Dropbox and more [2][7]. - An optional Pro console costs $2 per machine a month, billed yearly, and adds alerts, remote management and 100 GB of storage per machine [1]. - Remote file locking on S3, B2, Azure and Google Cloud stops locked backup files from being deleted or changed for a set period [5]. Verdict: Duplicati suits people who want free, encrypted backups to storage they choose, from a USB drive to Amazon S3 or OneDrive [3][7]. It sends only changed blocks, runs on a schedule and can lock backups against deletion on supported clouds [2][3][5]. Full-disk backups are documented, but Duplicati does not describe its own rescue media, so a full restore starts from separate recovery media [4]. Best for: People who want free encrypted backups to cloud storage they already pay for. ## Points | Criterion | Line | Value | Points | Note | |---|---|---|---|---| | What it backs up | Full system image | Yes | 8/8 | Backs up whole disks with the partition table and boot data; a disk restored to a blank drive starts up [4]. | | What it backs up | File and folder backup | Yes | 4/4 | You pick the files and folders to back up in the source picker [8]. | | What it backs up | Incremental backups | Yes | 6/6 | After the first run, Duplicati sends only changed blocks [2][3]. | | What it backs up | Scheduled backups | Yes | 4/4 | A built-in scheduler runs backups automatically [3][8]. | | What it backs up | Bootable rescue media | Not published | 0/8 | The docs say a full restore usually starts from separate recovery media [4]. | | Where backups go | Destinations | Local or USB drive, Network share or NAS, Vendor's own cloud, Other cloud storage | 20/20 | Local folders, SFTP or SMB storage, Duplicati Storage with the console, and S3, B2, OneDrive, Google Drive and more [2][7]. | | Safety and recovery | Encrypted backups | Yes | 7/7 | AES-256 encryption before upload, with a passphrase you set [3][8]. | | Safety and recovery | Backups shielded from ransomware | Yes | 6/6 | Remote file locking keeps backup files from being deleted or changed for a set period on S3, B2, Azure and Google Cloud [5]. | | Safety and recovery | Restore to different hardware | Not published | 0/6 | | | Safety and recovery | Versions and retention rules | Yes | 6/6 | Keep a number of versions, delete versions older than a period, or set a custom retention policy [6]. | | Price | Free edition | Yes | 10/10 | The open-source client is free [3]. | | Price | First-year price, one PC | $24/yr | 8/8 | Pro console, $2 per machine a month billed yearly; the backup client itself is free [1]. | | Price | One-time licence | Yes | 7/7 | The backup client is free and open source, so no subscription is needed [3]. | ## Plans | Plan | Price | Per month (USD) | |---|---|---| | Open-source client | Free [3] | $0 | | Console Free | Free [1] | $0 | | Console Pro | $2 per machine/month, billed yearly [1] | $2 | The Pro console lists $2.50 crossed out and $2 per machine a month on annual billing [1].
