| Bucket Name |
Set the name of the bucket. The name of a bucket cannot be changed after the bucket
is created.
The bucket name must comply with the following conventions:
- The name must be globally unique.
- The name can contain only lowercase letters, digits, and hyphens (-).
- The name must start and end with a lowercase letter or digit.
- The name must be 3 to 63 bytes in length.

| Region |
Select the region where the bucket is located. The region of a bucket cannot be changed
after the bucket is created.
To access the bucket from an ECS instance over the internal network, select the region
in which the ECS instance is located. For more information, see OSS domain names.
Notice If the bucket that you want to create is located in a region in mainland China, you
must complete real-name registration by submitting your relevant information on the
Real-name Registration page.

| Zone-redundant storage |
OSS provides zone-redundant storage (ZRS) to replicate user data across three zones
within the same region. Even if one zone becomes unavailable, the data still remains
accessible.
- Enable: Enable ZRS for the bucket. Objects in the bucket are stored by using ZRS. For example,
if the storage class of the bucket is Standard, the objects in the bucket are Standard
ZRS objects by default. For more information, see ZRS.
Notice
- ZRS is available only in the China (Shenzhen), China (Beijing), China (Shanghai),
China (Hong Kong)and Singapore regions.
- You can enable ZRS for a bucket only when you create the bucket. ZRS cannot be disabled
after you enable it for a bucket. Exercise caution when you enable this feature.
- Disable: Disable ZRS for the bucket. By default, ZRS is disabled for a bucket to be created.
Objects in the bucket are stored by using locally redundant storage (LRS). For example,
if the storage class of the bucket is Standard, the objects in the bucket are Standard
ZRS objects by default.
