Duplicati vs restic

Duplicati is backup software for Windows, macOS and Linux, covering computers and servers. It can back up desktops, laptops, local servers, NAS devices, Microsoft 365, Google Workspace and S3 buckets. Destinations include S3, WebDAV, SFTP and local hardware; cloud data can also be copied to an on-prem SAN or private S3 cluster. Data is encrypted locally with AES-256 before transfer, and only changed blocks are sent. Retention settings can remove older backups or keep a chosen number. Administrators can distribute backup configurations to clients, delegate local management to regional IT staff and isolate clients in sub-organizations. One subscription supports unlimited clients and endpoints. The free plan provides an insights dashboard, monitoring for up to two machines and access to the last 200 backups. Pro adds alerts, AI analysis, remote management, retention, storage and priority support. Enterprise adds organization management, configuration assistance, SSO with MFA, agent deployment and credential management. Pro is $2/mo billed annually; Enterprise is $3/mo billed yearly and requires at least 10 machines.

restic is a free, open-source program for backing up files on Linux, macOS, Windows, and BSD. It transfers only changed portions of backed-up files and runs as a single executable without a server or complex setup. Storage options include local repositories, SFTP, REST server, Amazon S3, S3-compatible services, OpenStack Swift, Backblaze B2, Azure Blob Storage, Google Cloud Storage, and rclone. Restic restores snapshots and checks repository metadata or full data integrity. Each repository requires a password, and multiple keys can be managed; losing the password prevents access to stored data. Official binaries are reproducibly built and can be checked with SHA-256 checksums and a PGP signature. The listed backup and restore scope is files. Mobile backup and ransomware protection are listed as unavailable. The latest listed release is restic 0.19.1, released July 5, 2026.
