- Add mysql_backup.sh: mysqldump to backup.sql.gz with proper restore hook (old --tab backup had no restore hook → restored backup silently lost DB data) - Update db backupbot labels: pre-hook → /mysql_backup.sh backup, restore.post-hook → /mysql_backup.sh restore - Fix app healthcheck start_period 1m → 15m (Ghost fresh-DB migration takes ~6-9min on slow hosts; old 1m caused migration lock deadlocks on deploy) - Fix db healthcheck start_period 1m → 15m (InnoDB init on fresh data dir ~6-10min) - Add MYSQL_BACKUP_VERSION=v1 to abra.sh
Upgrade ghost image from 6.21.2-alpine to 6.43.1-alpine (same major, no breaking changes). Keep MySQL at 8.0 — Ghost only supports MySQL 8 in production; MySQL 9 is not supported.
