Final answer:
Using a lifecycle policy to expire incomplete multipart uploads helps free up storage space and optimize storage management.
Step-by-step explanation:
A lifecycle policy is used to expire incomplete multipart uploads in order to free up storage space and maintain efficient storage management. Incomplete multipart uploads can occur when a large object is being uploaded to a cloud storage service and the upload process is interrupted or not completed. These unfinished uploads can take up valuable storage space and cause unnecessary costs.
By setting up a lifecycle policy to automatically expire incomplete multipart uploads after a certain period of time, you can ensure that storage resources are used effectively. The policy can be configured to delete the incomplete uploads, freeing up space for other files and reducing storage costs.
For example, if a user starts uploading a large video file to a cloud storage service but the upload is interrupted or abandoned, the incomplete multipart upload remains in storage indefinitely unless a lifecycle policy is in place. With a policy in place, the storage service can automatically detect and remove these unfinished uploads, optimizing storage resources.
