How Can I Periodically Delete Backup Files from a Bucket or Change the Storage Class of Backup Files?

This section applies to the following scenarios:

• Some files uploaded periodically need only to be retained for only one week or one month. You need to delete the files after they expire.
• Files are seldom accessed after a certain period of time. These files need to be transitioned to Infrequent Access or Archive storage or be deleted.

You can create lifecycle rules for objects in the preceding scenarios.

• Use an independent bucket to store backup files to prevent important files from being deleted by mistake during the periodical deletion.
• Apply the lifecycle rules to the entire bucket when configuring the lifecycle management function to manage the lifecycle of all objects in the bucket.
