Abstract
To manage expired backups in a storage system, a backup server retrieves multiple deletion logs which record invalid data included in one or more expired backups. When a deletion condition is met, the backup server identifies a first large object based on the multiple deletion logs, and sends a data migration request to an object-based storage system to instruct the object-based storage system to copy valid data of the first large object to a second large object. Thereafter, the backup server sends an object deletion request to the object-based storage system to instruct the object-based storage system to delete the first large object, thereby clearing up the expired backups.
