Astacus: Cloud Storage Backup and Restore Tool for Apache Cassandra
summary
Astacus is a Python tool that coordinates per-node backup and restore for Apache Cassandra via a REST-like coordinator API and HTTP inter-node calls, using nodetool snapshots, local or cloud object storage and deduplicated blob manifests. It supports compression and optional client-side encryption, stores manifests referencing hashed SSTable blobs, and enforces availability-zone balance and a requirement to restore onto at least the original node count. A demo restores a 3-node local CCM cluster successfully end-to-end.
