Direct-to-Cloud Backup Using Local Volume Failover During Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data backup systems to cloud storage are unreliable due to dependence on continuous internet connectivity, leading to potential data loss during connectivity interruptions or failures.
Innovation Solution
Implementing a local volume failover mechanism where computing device backups are stored locally on a second logical volume when connectivity to the cloud is lost, with incremental backups performed on this volume until connection is restored, and subsequently merged with the cloud backup chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud backup is performed continuously, then data security is improved, but system reliability deteriorates due to dependence on internet connectivity
Solution Approach 1:
The backup system dynamically switches between cloud backup mode and local failover mode based on internet connectivity status. When connectivity is available, backups are sent to cloud storage; when connectivity is lost, the system automatically transitions to storing backups locally on a second logical volume, ensuring continuous backup operation regardless of network conditions
Solution Approach 2:
A second logical volume is introduced as an intermediary storage layer between the primary data volume and cloud storage. This intermediate local storage acts as a buffer that accepts backups when cloud connectivity is unavailable, then transfers them to cloud storage when connectivity is restored, decoupling the backup process from direct internet dependence
2Reliability
If local failover volume is implemented, then backup reliability is improved during outages, but device complexity increases
Solution Approach 1:
The storage system is segmented into two distinct logical volumes: a first logical volume containing the primary operating system and data, and a second logical volume dedicated to backup storage and cloud connectivity management. This segmentation allows independent management of backup operations and failover logic without affecting primary system operations
Solution Approach 2:
The backup agent automatically monitors internet connectivity status and self-manages the backup destination selection without user intervention. The system autonomously determines whether to backup to cloud storage or local failover volume, and automatically transfers backups from local to cloud storage when connectivity is restored, eliminating the need for manual configuration or user awareness of the complexity

AI summary
The disclosure provides methods and systems for direct-to-cloud backup with local volume failover. According to an exemplary embodiment, first and second logical volumes are designated on a protected computing device. The first and second logical volumes may be paired to a cloud storage facility. In response to a received signal, it may be determined if the protected computing device has a communication connection to the cloud storage facility. If the protected computing device does have a communication connection to the cloud storage facility, a first computing device backup of the first logical volume may be sent to the cloud storage facility. If the protected computing device does not have a communication connection to the cloud storage facility, a second computing device backup of the first logical volume may be performed and stored on the second logical volume of the protected computing device.
