Creating Bucket

Last updated: 2024-01-06 14:59:34

Overview
You can create a bucket on the Bucket List page in the COS console. For more information on buckets, see Bucket Overview.
Note: 
 Each account can create up to 200 buckets regardless of the region.
Directions
1. Log in to the COS console.
2. Click Bucket List on the left sidebar.
3. Click Create Bucket.
4. In the pop-up Create Bucket dialog box, configure the following information:
1. Basic information
﻿
Region: A COS region corresponding to the physical location where your business or users are distributed. This parameter cannot be modified once configured. For more information on regions, see Regions and Access Endpoints.
Name: A custom bucket name, which cannot be modified once configured. For more information, see Bucket Overview > Bucket Naming Conventions.
Access Permissions: Three access permissions are available for buckets by default: "Private Read/Write", "Public Read/Private Write", and "Public Read/Write". You can modify it if needed. For more information, see Setting Access Permission.
Endpoint: The value is generated automatically. After creating a bucket, you can use this endpoint to access the bucket.
2. Advanced settings
Note: 
 Advanced settings are optional and can be set as needed.
﻿
Versioning: If this field is enabled, and you upload an object whose name already exists, the historical version will be retained.
MAZ configuration: It is a bucket flag. When you enable it, your data will be stored in different data centers in the same region for intra-region disaster recovery. Currently, this feature is only available in certain regions such as Beijing, Shanghai, Guangzhou, and Singapore. For more information, see Overview of Multi-AZ Feature.
Note: 
Enabling MAZ configuration for a bucket will also enable versioning. After MAZ configuration is enabled, it cannot be modified, and data will be stored in the bucket in an MAZ storage class, such as MAZ_STANDARD and MAZ_STANDARD_IA. Configure it with caution.
Multi-AZ cannot be enabled for existing buckets. It can be enabled only for new buckets during creation.
Logging: Stores logs of bucket-related requests.
Bucket Tag: A tag is used as an identifier to manage buckets. For more information, see Setting Bucket Tag.
Server-Side Encryption: Currently, the only supported bucket encryption method is SSE-COS encryption (i.e., server encryption using COS-managed keys). For more information on server encryption, see Server-Side Encryption Overview.
