Hardened Kubernetes backup: Velero with its AWS plugin, backing up to SeaweedFS over S3 in the same install, with generated keys, a bucket created at install and the backup location already configured.

Version

0.0.9 · latest0.0.80.0.7

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
