Does OBS Support Storage Quota Management?

OBS allows you to manage the storage quota for buckets.

By default, the storage space of a bucket is not limited. You can configure a quota to limit a bucket's storage space that can be used. If the configured storage quota is used up, object upload will fail.

Quota management is currently not available for parallel file systems. By default, there is no quota limit.

A quota takes effect 15 minutes after its configuration is complete. OBS checks whether the quota has been used up 15 minutes later each time the storage statistics are collected. If OBS checks that the storage quota has been used up when objects are being continuously written to a bucket, no more objects can be written to the bucket. Therefore, in some cases, the actual capacity of a bucket may be slightly greater than the configured storage quota.

Bucket Quota Configuration

Manage bucket storage quotas using OBS Console and APIs.

For details about how to configure a storage quota using APIs, see the API for quota configuration in the API Reference.

The following procedure describes how to configure a storage quota on OBS Console.

In the navigation pane, choose Overview.
In the Basic Configurations area, click the Storage Limit card to change the limit on the current bucket's storage.
By default, the storage capacity is not limited. The minimum quota allowed is 1 MB.
Click OK.
