Backup for ${NS} — ${TIMESTAMP}
|
|
==================================
|
|
|
|
Instance: ${NAME} (namespace: ${NS})
|
|
Chart: matrix-2.9.17 (old chart, NOT ESS)
|
|
Dump PG: Synapse (chat-postgresql) + MAS (mas-postgresql)
|
|
|
|
Files:
|
|
dump-synapse.sql Synapse PostgreSQL dump (pg_dump -U postgres -d matrix)
|
|
dump-mas.sql MAS PostgreSQL dump (pg_dump -U mas -d mas)
|
|
synapse-media.tar.gz Synapse media files (/data/media_store/)
|
|
secret-chat-matrix.yaml Synapse secrets (signing.key, macaroon, etc.)
|
|
secret-chat-postgresql.yaml PG passwords
|
|
secret-mas.yaml MAS secrets (encryption-key, signing-key, shared-secret)
|
|
secret-matrixrtc-livekit.yaml LiveKit secrets
|
|
|
|
CRITICAL for restore:
|
|
- secret-chat-matrix.yaml (SYNAPSE_SIGNING_KEY for federation identity)
|
|
- secret-mas.yaml (MAS encryption-key for user sessions)
|
|
- dump-synapse.sql (all user data, rooms, messages)
|
|
- dump-mas.sql (MAS user auth data)
|
|
|
|
Migration to ESS chart notes:
|
|
- The old chart uses separate Helm releases per component (chat, element-call, livekit).
|
|
- ESS bundles everything into the matrix-stack chart.
|
|
- PostgreSQL is external (CNPG) on the new cluster.
|
|
- MAS keys must be restored EXACTLY as-is for user auth to work.
|
|
- The Synapse signing.key MUST match the federation identity.
