Configuring Bucket Storage Quota

Functions

The bucket storage quota must be a positive integer in the unit of byte. The maximum storage quota is 263 – 1 bytes. The default bucket storage quota is 0, indicating that the bucket storage quota is not limited.

Note
  1. For a bucket that has a specified storage quota, you can change the quota to 0 to cancel the quota limitation.
  2. The bucket storage quota verification depends on how much space is used in the bucket. However, the used storage space is measured at the background. Therefore, bucket storage quotas may not take effect immediately, and delay is expected. The used storage space in a bucket may exceed the bucket storage quota, or the used storage space may remain unchanged after data is deleted from the bucket.
  3. For details about the API for querying used storage space, see Obtaining Storage Information of a Bucket.
  4. If the used storage space in a bucket reaches the upper limit of the bucket storage quota, object upload will fail and the HTTP status code 403 Forbidden will be returned, indicating InsufficientStorageSpace. In this case, you can increase the quota, cancel the quota limitation (by changing the quota to 0), or delete unwanted objects from the bucket.
