Before you start

You can use Kingsoft Cloud Archive Storage (KArchive) in the following three ways:

1. KS3 console Log in to the KS3 console in your browser. In the console, you can create a KArchive bucket, upload objects to the bucket, restore the objects, and change the storage class. For more information, see Operations in the KS3 console.
   
2. API operations You can call the API operations to use KArchive to flexibly meet your development requirements. For more information, see Archive Storage Related.
   
3. Lifecycle rules You can configure lifecycle rules to change the storage classes of objects. When an object stored in KS3 expires, the system automatically changes the storage class of the object to Archive based on the lifecycle rule. For more information about KS3, see Kingsoft Cloud Standard Storage Service. For more information about lifecycle management, see Manage lifecycle.
