Title:
期限切れバックアップ処理方法及びバックアップサーバ
Document Type and Number:
Japanese Patent JP6968876
Kind Code:
B2
Abstract:
The present invention provides an expired backup processing method. The method is performed by a backup server, and includes: Each time after an expired backup of first disk data is determined, the backup server creates a deletion log of the first disk data, and stores a pointer of invalid data in the expired backup into the deletion log, where the expired backup is an earliest backup in all unexpired backups of the first disk data that have been performed in an object-based storage system by a current first moment. Therefore, after subsequently detecting that a deletion condition is met, the backup server obtains a plurality of deletion logs corresponding to the first disk data, determines, based on the deletion logs, a large object that includes the invalid data and valid data, moves the valid data into another large object, and instructs the object-based storage system to delete the large object that includes the invalid data. In this way, expired backup processing is implemented for disk data that is incrementally backed up in a large object-based storage manner.
