Clair vs Duplicati
A side-by-side editorial comparison of Clair and Duplicati — release velocity, themes, recent moves, and the top alternatives to consider.
Clair vs Duplicati: at a glance
What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
What is Duplicati?
Duplicati's canary brings back one-click updates and restores disk backups to VHD files.
Duplicati 2.4.1 stable added delta backups for Microsoft 365 and Google Workspace and scheduled restore tests. The 2.4.1.101 canary brings back the automatic updater, now a helper that verifies and installs the signed package for each OS, lets a full disk backup be restored into a raw, VHD or VHDX image, and adds an on/off switch per backup. It also fixes a scheduler that silently used UTC and a case where a vanished USB or network destination was recreated empty.

Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
Duplicati
5.0INFRA · APIS
Duplicati's canary brings back one-click updates and restores disk backups to VHD files.
◆ Current state
Duplicati 2.4.1 stable added delta backups for Microsoft 365 and Google Workspace and scheduled restore tests. The 2.4.1.101 canary brings back the automatic updater, now a helper that verifies and installs the signed package for each OS, lets a full disk backup be restored into a raw, VHD or VHDX image, and adds an on/off switch per backup. It also fixes a scheduler that silently used UTC and a case where a vanished USB or network destination was recreated empty.
◆ Where it's heading
The canaries alternate between new restore paths and closing cases where Duplicati looked fine but wasn't, such as silent failures, wrong time zones and missing destinations. The updater makes it easier to keep desktop and server installs on the fixed versions.
◆ Prediction
Expect updater fixes in the next canaries, given that this is its first version, and the disk-image and scheduler work to move into the next stable.
