Backup Storage Capacity Management via Data Addition Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backup methods fail to distinguish between adding new data and updating existing data, leading to insufficient management of storage capacity usage, making it difficult to accurately comprehend the actual storage capacity used by users.
Innovation Solution
The solution differentiates between adding new data and updating existing data during the backup process, only increasing used capacity when new data is added, allowing for accurate management of storage capacity usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If backup processing treats adding new data and updating existing data as the same process, then the backup operation is simplified, but the storage capacity management becomes inaccurate
Solution Approach 1:
The backup processing is segmented into two distinct processes: one for adding new data and another for updating existing data. This segmentation allows the system to track storage capacity usage accurately by differentiating between operations that increase used capacity (adding new data) and operations that do not (updating existing data), thereby resolving the contradiction between operational simplicity and measurement accuracy.
2Device complexity
If the system tracks all backup operations uniformly, then the backup management is easier, but the accurate comprehension of actual storage capacity used becomes difficult
Solution Approach 1:
The system segments backup management into distinct tracking mechanisms for new data addition and existing data update. By maintaining separate process paths and tracking methods for each type of operation, the system can accurately comprehend actual storage capacity usage while keeping the overall management structure organized and manageable through clear process differentiation.

AI summary
The invention provides a storage subsystem in which a system administrator and a user can accurately comprehend the used storage capacity. Therefore, according to the backup of the present invention, a process for adding new data and a process for updating already existing data are distinguished, and a management to increase a capacity used by the user is performed only when adding new data.
