Power Save Mode for Continuous Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous data protection (CDP) processes on laptops and mobile devices consume excessive power due to compression, de-duplication, and encryption, reducing battery life when operating on battery power.
Innovation Solution
A power-save mode is implemented for the CDP process, where a CDP module monitors battery levels and configures the process to restrict operations such as compression, de-duplication, and encryption, extending battery life by adjusting settings across defined battery zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression, de-duplication, and encryption operations are performed continuously in the CDP process, then data protection reliability is improved, but power consumption increases
Solution Approach 1:
The CDP module dynamically adjusts its operation mode based on power availability. When AC power is detected, the system operates in full protection mode performing compression, de-duplication, and encryption. When battery power is detected, the system transitions to power-save mode, selectively disabling certain operations to reduce power consumption while maintaining essential data protection functionality.
Solution Approach 2:
The system changes operational parameters based on power source detection. Configuration settings are modified to enable or disable specific CDP operations (compression, de-duplication, encryption) depending on whether AC or battery power is available. This parameter adjustment allows the system to optimize between protection reliability and power consumption.
2Reliability
If the CDP process operates in normal mode with full processing operations, then data protection capability is improved, but battery runtime is reduced
Solution Approach 1:
The CDP module continuously monitors power source status and dynamically switches between normal operation mode and power-save mode. This dynamic adaptation ensures that the system maintains optimal data protection when AC power is available while conserving battery energy when running on battery power, thereby extending battery runtime without completely sacrificing protection capability.
Solution Approach 2:
In power-save mode, the system performs partial CDP operations rather than complete processing. Certain operations like compression or encryption may be disabled or deferred, performing only essential data protection functions. This partial action approach extends battery runtime while maintaining core data protection functionality.
3Reliability
If the CDP module performs all processing operations (compression, de-duplication, encryption), then data security is improved, but power usage increases
Solution Approach 1:
The system modifies operational parameters based on detected power source. When battery power is detected, configuration settings are changed to disable power-intensive operations such as compression, de-duplication, and encryption, or to perform them less frequently. When AC power is available, all processing operations are enabled to provide full data security. This parameter adjustment resolves the contradiction between security and power usage.
Solution Approach 2:
The CDP module dynamically adjusts its security processing level based on power availability. The system transitions between different operational states (full protection mode vs. power-save mode) depending on whether AC or battery power is detected, allowing flexible adaptation between security level and power consumption requirements.

AI summary
Technologies are described herein for providing a power-save mode of operation for a continuous data protection (“CDP”) process. A CDP module executing on a computer detects when the computer is operating under battery power, and enters a power-save mode of operation. In the power-save mode, the CDP module monitors the state of the battery and restricts the CDP process based on a set of configuration settings specified for one of a number of zones, where each zone defines an upper and lower thresholds for a level of charge of the battery. If external power is restored to the computer, the CDP module restores the normal mode of operation for the CDP process.
