Glacier

Core services → Projects

Core services · 1 — AWS basics · ~6 min · AWS — Storage & Databases

What is this?

S3 Glacier storage classes archive data at low cost with retrieval times from minutes to hours. Ideal for compliance retention.

Why should you care?

AwsVerse retains banking records seven years in Glacier Deep Archive for regulatory compliance.

See it live — copy this example

Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).

aws s3api put-object \
  --bucket awsverse-archive \
  --key records/2026/07/statement-batch.tar.gz \
  --body batch.tar.gz \
  --storage-class DEEP_ARCHIVE

What happened?

Uploads an object directly to Deep Archive tier.
Restore jobs take up to 12 hours; plan retrieval before audits.

Practice next

Create archive bucket with Object Lock (lab: skip lock).
Upload with --storage-class GLACIER_IR for faster retrieval tests.
Initiate restore: aws s3api restore-object ...
Set bucket lifecycle to Deep Archive after 365 days.
Compare Glacier Instant vs Flexible retrieval pricing.

Remember

Glacier = cheap long-term archive. Retrieval takes time and costs. Use lifecycle policies to transition.

AwsVerse 7-year retention

RBI audit needs 2019 statements.

Outcome: Bulk restore from Deep Archive completes before deadline.
