This enables full cluster recovery, fine-grained restores, and data portability across environments. https://plakar.io/posts/2026-02-07/storing-backups-in-an-oci-registry/ Sat, 07 Feb 2026 20:00:00 +0100 https://plakar.io/posts/2026-02-07/storing-backups-in-an-oci-registry/ After a podcast discussion, we implemented an OCI registry storage backend. This article discusses the concept and showcases our proof of concept. https://plakar.io/posts/2026-01-26/plakar-v1.1.0-beta-the-foundation-for-whats-next/ Mon, 26 Jan 2026 10:00:00 +0100 https://plakar.io/posts/2026-01-26/plakar-v1.1.0-beta-the-foundation-for-whats-next/ plakar v1.1.0-beta marks a major step forward, with significant performance gains, architectural simplifications, and powerful new user-facing features.
