about

nx_ha_replication.nx -- CAP-HA-REPLICATION: append-only log-shipping replication (WAL-style) to kill the DATA SPOF (the single NAS). The primary appends records; rep_ship copies new bytes to a standby/backup so it holds a BYTE-EXACT prefix of the primary. Usable TODAY as backup/DR (single-node), and the sync target when a standby host exists. Append-only = history sacred (never rewrites). Deterministic; rep_in_sync proves byte-identity, rep_lag measures how far behind the replica is. license_tier: ORIGINAL
