Lifecycle Management Best Practices¶

Use these practices to keep lifecycle rules explainable, testable, and safe to operate.

This page's baseline at a glance — the recommended practices and the validation gate:

Why This Matters¶

Lifecycle automation is powerful, but broad rules can delete or archive data faster than teams realize.

• Prefix and tag design determine whether policy scope is understandable.
• Policy execution is not immediate, so verification matters.
• Destructive lifecycle actions should be paired with recovery controls where needed.

Recommended Practices¶

• Translate policy intent into clear prefixes and tags.
• Move data through tiers with timing that reflects business usage, not guesswork.
• Pair delete actions with soft delete, versioning, or backup when recovery still matters.
• Review rule interactions whenever new datasets or prefixes are added.
• Validate policy outcomes with representative blobs after changes.

Example policy command¶

cat > lifecycle-policy.json <<'EOF'
{
  "rules": [
    {
      "enabled": true,
      "name": "archive-old-logs",
      "type": "Lifecycle",
      "definition": {
        "filters": {
          "blobTypes": ["blockBlob"],
          "prefixMatch": ["logs/"]
        },
        "actions": {
          "baseBlob": {
            "tierToCool": { "daysAfterModificationGreaterThan": 30 },
            "tierToArchive": { "daysAfterModificationGreaterThan": 180 },
            "delete": { "daysAfterModificationGreaterThan": 365 }
          }
        }
      }
    }
  ]
}

Common Mistakes / Anti-Patterns¶

• Rules nobody can explain: If operators cannot say which prefixes a rule affects, it is too broad.
• Delete first, recover later: Recovery controls should be agreed before destructive automation is enabled.
• Control-plane success only: A policy that saves successfully still needs blob-level validation later.

Validation Checklist¶

• [ ] Prefixes or tags clearly define policy scope.
• [ ] Tier timing reflects real business access patterns.
• [ ] Delete rules are paired with recovery controls where appropriate.
• [ ] Policy changes are reviewed for interaction with existing rules.
• [ ] Sample blobs are validated after policy updates.
