Operations

This section covers day-to-day operation of a Big Bang deployment that’s already running — monitoring, backup and recovery, upgrades, and troubleshooting. It does not cover initial deployment; see Getting Started for that.

What You’ll Find Here

Operating a running deployment breaks down into three areas:

• Day-to-day operations — cluster health, through monitoring.
• Lifecycle management — data protection through backup and restore, and moving through Big Bang’s two-week release cadence via planned upgrades.
• Issue resolution — troubleshooting guides organized by symptom, not by component, so you start from what you’re observing

Find the Right Starting Point

Your goal	Start here
Set up observability and alerting	Monitoring — put this in place before an incident, not during one
Protect your data	Backup and Restore — and actually test the restore, not just the backup
Upgrade Big Bang or a package	Upgrades — plan your cadence deliberately; Big Bang releases every two weeks
Automate dependency updates	Maintenance, including Renovate
Diagnose a specific problem	Troubleshooting — worth a skim before you need it, organized by symptom: installation, networking, packages, performance, upgrades
