+# Object storage tiers
+
+Tigris offers object storage tiers to optimize storage costs based on the access
+patterns of your data. There are three storage tiers available:
+
+- Standard
+- Infrequent Access
+- Archive
+
+## Standard tier
+
+The default storage class. It provides high durability, availability, and
+performance for frequently accessed data.
+
+## Infrequent Access tier
+
+Lower-cost storage for data that is accessed less frequently but requires rapid
+access when needed.
+
+## Archive tier
+
+Low-cost storage for data archiving. Long-term data archiving with infrequent
+access. The data is not immediately available for access and requires restoration 
+before it can be accessed. Restoration time is about 1 hour.
+
+## Setting object tier
+
+The default tier for all objects stored in a particular bucket can be specified in the
+[bucket configuration](../buckets/create-bucket.md#setting-bucket-tier) during bucket creation time.
+If no tier is provided at bucket creation time, it defaults to Standard.
+
+Object tier can also be set at the object creation time.
+This overrides the tier specified in the bucket configuration. To set the object tier, use the `--storage-class` flag with the
+`put-object` AWS CLI or corresponding field of PutObject, CreateMultipartUpload
+SDK APIs input. REST API users can set the `x-amz-storage-class` header.
+
+Tigris accepts S3 compatible storage classes:
+
+- STANDARD - for standard
+- STANDARD_IA - for infrequent access
+- GLACIER - for archive
+
+### Example with AWS CLI
+
+```bash
+aws s3api put-object --bucket my-bucket --key my-object.txt --body bar.txt --storage-class STANDARD_IA
+```
+
+### Example with REST API
+
+```http
+PUT /my-object.txt HTTP/1.1
+Host: my-bucket.storage.fly.tigris.dev
+x-amz-storage-class:STANDARD_IA
+```
+
+## Restoring objects from Archive tier
+
+Objects written to the Archive storage class are not immediately available for
+access. Get requests for objects in the Archive storage class will return 403
+(InvalidObjectState) error. To restore objects from the Archive storage class,
+initiate a restore request.
+
+### Initiate restore request
+
+```bash
+aws s3api restore-object --bucket my-bucket --key 'my-archive-object.txt' --restore-request Days=3
+```
+
+The `Days` parameter specifies the number of days the restored object will be
+available for access. After the specified number of days, the object will be
+moved back to the Archive storage class.
+
+### Check restore status
+
+```bash
+aws s3api head-object --bucket my-bucket --key 'my-archive-object.txt'
+```
+
+Ongoing restore requests will have the `Restore: ongoing-request="true"` header
+in the response. Once the restore is complete, the `Restore` header will contain
+the expiry date when the object will be moved back to the Archive storage class:
+
+```bash
+{
+    "Restore": "ongoing-request=\"false\" expiry-date=\"Fri, 01 Nov 2024 02:00:00 GMT\"",
+    "StorageClass": "GLACIER"
+}
+```
