Backup and Restore

Backup model

Astra can use object-tier storage for manifests and chunk data, and the single-node production path can also ship daily archive copies to external S3-compatible storage such as Cloudflare R2.

What to back up

• Astra local state roots
• object-tier manifests and chunks
• K3s token and config material for Astra-backed K3s deployments
• deployment summaries and last-known-good endpoint configuration

Validate backups

• confirm manifests and chunk counts exist where expected
• validate object accessibility and checksums
• record the latest known-good manifest or archive prefix
• run restore drills instead of assuming uploads are enough

Restore model

• start from clean local node state
• restore the latest validated manifest or archive set
• confirm key parity and revision visibility before admitting writes
