Database Backup Checkpoint Resume Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database backup systems often restart interrupted backup operations from scratch, leading to inefficiencies and potential data loss, rather than resuming from the last updated checkpoint.
Innovation Solution
A method and system that allow for resuming both full and incremental database backup operations from identified checkpoints, utilizing a client protection agent and backup storage system to manage backup tags and checkpoints, enabling seamless continuation of interrupted operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interrupted backup operations are restarted from scratch, then the backup system ensures data consistency, but the backup time and productivity are significantly increased
Solution Approach 1:
The system performs preliminary actions by creating and storing checkpoint information during the backup process. When a backup operation is interrupted and restarted, the system uses these pre-established checkpoints to resume from the last successful point rather than starting over, thus maintaining data consistency while reducing redundant backup time
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring backup operation status and updating checkpoint information. When an interruption is detected, the system uses this feedback to determine the appropriate resume point, ensuring that the backup can continue from a valid state without compromising data consistency
2Device complexity
If interrupted backup operations are restarted from scratch, then the backup process is simplified, but the loss of time and efficiency are increased
Solution Approach 1:
Checkpoint information is preliminarily established and stored during normal backup operations. This preliminary action enables the system to quickly identify resume points without complex analysis when interruptions occur, balancing process simplicity with time efficiency
Solution Approach 2:
The backup system serves itself by automatically managing checkpoint creation, storage, and retrieval. This self-service mechanism handles the complexity of checkpoint management internally, keeping the user interface simple while enabling efficient resume operations that reduce time loss
3Productivity
If checkpoint management is implemented for resume operations, then the efficiency and data protection are improved, but the system complexity is increased
Solution Approach 1:
The system extracts checkpoint management as a separate, dedicated function within the backup system. By isolating checkpoint creation, storage, and retrieval operations into distinct components, the system improves backup efficiency through targeted checkpoint usage while managing complexity through functional separation
Solution Approach 2:
The checkpoint mechanism is designed as a universal component that serves multiple functions: tracking backup progress, enabling resume operations, and ensuring data consistency. This multi-functionality improves overall system productivity while avoiding the need for separate mechanisms for each function, thereby controlling system complexity

AI summary
In general, the invention relates to a method for backing up data. The method includes receiving a backup instruction from a client device, wherein the backup instruction comprises a backup tag corresponding to a backup operation for a user asset, making a first determination that the backup tag matches a second backup tag specified in a tag file, and in response to the first determination, identifying a checkpoint of a backup associated with the second backup tag, and resuming the backup operation at the checkpoint for the user asset.
