Snapshot & Storage Decommission¶

💾 Storage Cost Optimization | Commands: runbooks finops ec2-snapshots, runbooks finops optimize-s3-lifecycle

Overview¶

Identify orphaned snapshots, unused S3 buckets, and optimize storage tiering with lifecycle policies.

When to Use¶

Scenario	Command	Savings Potential
Monthly Snapshot Cleanup	`runbooks finops ec2-snapshots --all-profiles --delete-unattached`	$200-$500/month
S3 Lifecycle Optimization	`runbooks finops optimize-s3-lifecycle --all-profiles`	$800-$1500/month
Deep Archive Planning	`runbooks finops analyze-s3-storage-lens --all-profiles`	Variable by data age

Usage Examples¶

Example 1: Orphaned Snapshot Removal (3 min)

runbooks finops ec2-snapshots \
  --all-profiles \
  --delete-unattached \
  --output-dir ./snapshot-audit

# Output: snapshot-audit/removal-plan.csv
# 250+ orphaned snapshots:
# - Total storage: 1,250 GB
# - Monthly waste: $800-$1200
# - Action: Automatically delete unattached
# - Confidence: 100% (safe - no attached volumes)

Example 2: S3 Lifecycle Policy Recommendations (5 min)

runbooks finops optimize-s3-lifecycle \
  --all-profiles \
  --format pdf \
  --output-dir ./reports

# Output: S3 lifecycle recommendations:
# - Standard to Infrequent Access (90 days): $150/month
# - Infrequent Access to Glacier (180 days): $200/month
# - Glacier to Deep Archive (365 days): $100/month
# - Delete old logs (730 days): $50/month
# Total savings: $500/month with policy implementation

Example 3: Storage Lens Cost Analysis (2 min)

runbooks finops analyze-s3-storage-lens \
  --all-profiles \
  --breakdown-by-bucket

# Output: Per-bucket cost:
# - Bucket A (logs): 150GB Standard → 50GB Glacier (save $120/mo)
# - Bucket B (data): 500GB mixed → optimize tiering (save $180/mo)
# - Bucket C (archive): Already optimized

Enrichment Signals¶

Signal	Definition	Data Source
S1	Storage class cost	S3 Pricing API
S2	Object age distribution	S3 Inventory reports
S3	Access frequency	S3 Storage Lens metrics
S4	Request patterns	CloudTrail (S3 API calls)
S5	Encryption overhead	AWS KMS usage metrics
S6	Replication cost	S3 metrics (cross-region)

detect-orphans - Cross-resource cleanup (including old snapshots)
analyze-s3-storage-lens - Storage distribution analysis
optimize-cloudwatch-costs - Log storage optimization (paired with S3)

MCP Validation¶

Storage optimization validated at ≥99.5% accuracy using S3 Inventory, Storage Lens, and CloudTrail.
