Application Group Checkpointing for Multi-Service Recovery

The patent segments the storage checkpointing mechanism from the storage subsystem level to the application level. Instead of checkpointing entire storage devices or partitions, the system creates application-specific checkpoints that only affect individual applications. This is achieved by implementing checkpointing at the file system or application data level, allowing selective recovery of specific applications without impacting other applications on the same storage device.

The patent applies local quality by making checkpointing effects localized to specific applications rather than globally affecting all applications on the storage device. Each application can have its own checkpoint markers and recovery processes, ensuring that storage recovery operations are confined to the local scope of the affected application only.

The patent implements a universal checkpointing mechanism that can protect multi-application services composed of applications from different vendors. The system provides a common framework that works across diverse applications, creating a unified protection layer that handles checkpointing, recovery, and coordination for multiple independent applications simultaneously, regardless of their vendor origins or loading times.

The patent introduces an intermediary checkpointing management system that coordinates between multiple independent applications. This intermediary layer handles the complexity of protecting multi-application services by managing checkpoints, recovery sequences, and coordination without requiring modifications to the individual applications themselves, thus preserving vendor independence while providing comprehensive protection.
