What it is

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.
