Duplicati v2.3.0.110_canary_2026-08-25

This release is a canary release intended to be used for testing.

Database update to version 20

This release updates the local database schema to version 20. The update adds a label column to the fileset table and is applied automatically on first use. After the update, the database can no longer be opened by earlier versions of Duplicati. If you need to downgrade, the bundled database tool (duplicati-database-tool) can downgrade the database back to version 19; downgrading removes the labels, but otherwise causes no data loss.

Labels on backup versions

Backup versions can now carry an optional text label. Labels have no functional purpose, but they help mark and distinguish versions, for example when backups are hand-curated instead of running on a schedule. The CLI and UI supports setting and showing labels.

Partition-level backup and restore

It is now possible to select a single disk partition as the backup source, instead of selecting the full disk and filtering the unwanted partitions. Restores are likewise more flexible: in addition to disk-to-disk restores, a single partition can now be restored into a partition on another disk, creating the partition as needed.

This also fixes a bug where a failing priority file would leave the restore stuck until it was cancelled, and a number of issues with enumerating and filtering disks and partitions, in particular on Windows.

Automatic metadata storage for sources that need it

Backups using a source provider that relies on database metadata, such as the disk image provider, previously required the user to set --store-metadata-content-in-database=true manually. The setting is now applied automatically when the source needs it, and can still be overridden by setting the option explicitly.

QNAP packages

This release adds native QNAP package support. Similar to the Synology package, it integrates with the QNAP OS, uses the built-in authentication, and only allows access for administrators.

Stricter Google Cloud Storage credentials

Google Cloud Storage credentials are now read as service account credentials, which is what the options are documented to take. Other credential types, such as stored user credentials or external account configurations, are now refused. If you authenticate to Google Cloud Storage, or the Google Cloud secret provider, with anything other than a service account key, you need to switch to a service account key.
