    Storage Class

    OBS has the following storage classes: Standard, Infrequent Access, and Archive. In such a manner, OBS comprehensively meets customers' requirements on storage performance and costs.

    • OBS Standard: features low access latency and high throughput.
    • OBS Infrequent Access: applicable to storing semi-frequently accessed (less than 12 times a year) data that requires quick response.
    • OBS Archive: applicable to storing rarely accessed (once a year) data.

    For details about the storage classes, see Storage Classes.

    Bucket Name

    Enter the bucket name, which must be globally unique.

    Name the bucket according to the globally applied DNS naming rule as follows:

    • Contains 3 to 63 characters, including lowercase letters, digits, hyphens (-), and periods (.)
    • Cannot be an IP address.
    • Cannot start or end with a hyphen (-) or period (.)
    • Cannot contain two consecutive periods (.), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
