<h3 id="q-how-often-are-backups-taken"><a class="header" href="#q-how-often-are-backups-taken">Q: How often are backups taken?</a></h3>
|
|
<p><strong>A</strong>: Hourly for database (1-hour RPO), daily for configs/IaC. Monthly restore tests verify backups work.</p>
|
|
<h3 id="q-how-long-does-recovery-take"><a class="header" href="#q-how-long-does-recovery-take">Q: How long does recovery take?</a></h3>
|
|
<p><strong>A</strong>: Depends on scenario. Pod restart: 2-3 min. Database recovery: 15-60 min. Full cluster: 2-4 hours.</p>
|
|
<h3 id="q-how-much-data-can-we-lose"><a class="header" href="#q-how-much-data-can-we-lose">Q: How much data can we lose?</a></h3>
|
|
<p><strong>A</strong>: Maximum 1 hour (RPO = 1 hour). Worst case: lose transactions from last hour.</p>
