Duplicati
What it is
Duplicati is backup software for Windows, macOS, and Linux, covering computers and servers. It can protect desktops, laptops, local servers, NAS devices, Microsoft 365, Google Workspace, and S3 buckets. Backups can go to S3, WebDAV, SFTP, or local hardware; cloud data can also be copied to an on-prem SAN or private S3 cluster. Duplicati encrypts data locally with AES-256 before transfer and sends only changed blocks. Retention rules can delete older backups or preserve a chosen number. Administrators can create configurations for multiple clients, delegate local backup management, and separate clients into sub-organizations. A subscription supports unlimited clients and endpoints. The free plan includes an insights dashboard and monitoring for up to two machines, with 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 a month billed annually; Enterprise is $3 a month, billed yearly, with a minimum of 10 machines and a yearly contract.
