Limiting the maximum size of a bucket
Object Storage lets you limit the maximum size of a bucket.
If, for example, you provide the users of your service the ability to upload objects to Object Storage, then by limiting the maximum volume, you can better control user actions and avoid unnecessary spending.
In the management console, select the appropriate folder.
Select Object Storage.
Click the name of the desired bucket.
Go to the Settings tab.
Set the Max size field value.
0, the maximum size isn't limited. It's similar to the enabled No limit option.
