How to update the Duplicati Encrypted backup client

Read the release notes first — self-hosted projects break config and schemas between versions more often than appliances do.
Docker: pull the new image tag and recreate the container (`docker compose pull && docker compose up -d`).
Package or bare metal: update through your distribution's package manager, or replace the binary from the releases page.
Back up the config and database directory first. For most projects a downgrade is not supported once the schema has migrated.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.

FAQ

How do I update the Duplicati Encrypted backup client?

See the step-by-step above. Open the NAS control panel, go to the update or system section, and install the new version. Back up important data first; NAS updates can take several minutes.

How does Firmwarely know when there's a new version?

Every night we read the manufacturer's official release page for the Duplicati Encrypted backup client and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official Duplicati page?

No. Firmwarely is independent. Device and brand names belong to their manufacturers; always download firmware from the official source.
