Object Storage: Buckets & Lifecycle Rules

Objects, buckets, namespaces

Object Storage is for files, images, backups and archives — not for databases. Each object has a key (its path), data and metadata; objects live in a bucket, buckets under a region in your tenancy’s object-storage namespace.

Create a bucket (10 GB free)

oci os bucket create \
  --namespace $NS --name groovygrails-books \
  --compartment-id $COMP_OCID
# core of the namespace is in your tenancy info; list it with:
oci os ns get

Or click Object Storage & Archive Storage → Buckets → Create Bucket. Decide:

• Visibility: keep Private unless the objects are meant for the public.
• Versioning + Object lock: turn on for backup buckets — protects against accidental deletion/overwrite.

Lifecycle rules automate hygiene

Add a Lifecycle Rule so untouched objects auto-tier after a set number of days — free bucket management without scripts:

oci os bucket update \
  --namespace $NS --bucket-name groovygrails-books \
  --lifecycle-policy-rules-file rules.json
# rules.json:
# {
#   "items": [{
#     "action": "ARCHIVE",
#     "timeAmount": 30, "timeUnit": "DAYS",
#     "isEnabled": true
#   }]
# }

30 days → ARCHIVE (cheap, durable, still retrieved on demand). Combined with versioning you get accidental-delete protection and automatic archival cost savings in one rule.
