If your storage is node-local (a <code>local-path</code> or <code>hostPath</code> volume pinned to one node), you&rsquo;re restoring from backup and praying it&rsquo;s recent. Ceph gives you replication but demands 3+ dedicated storage nodes, a PhD in CRUSH maps, and constant tuning. Most teams either over-invest in storage infrastructure or under-invest and pay the price in outages.</p>
