SYSTEM AND METHOD FOR AVOIDING UNWANTED LOG TRUNCATION (DATA LOSS) DURING APPLICATION CONSISTENT VIRTUAL MACHINE SNAPSHOTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17966503 titled 'SYSTEM AND METHOD FOR AVOIDING UNWANTED LOG TRUNCATION (DATA LOSS) DURING APPLICATION CONSISTENT VIRTUAL MACHINE SNAPSHOTS

Simplified Explanation

The abstract describes a patent application for a system where a data protection agent within a virtual machine coordinates with a copy service and a snapshot data mover to backup data from an application in the VM to secondary storage.

• The data protection agent installed within a virtual machine issues a request to freeze an application to a copy service.
• A request for a snapshot is sent to a snapshot data mover external to the VM.
• After receiving a snapshot identifier, the agent communicates with the copy service to thaw the application and access the snapshot for data rollover to secondary storage.
• The copy service is notified of the backup success or failure based on status updates during the rollover process.

Potential Applications

The technology described in the patent application could be applied in various industries where data protection and backup solutions are required, such as:

• Cloud computing
• Data centers
• Enterprise IT environments

Problems Solved

This technology addresses the following issues:

• Efficient data backup and protection within virtual machines
• Coordinating backup processes between different services and components
• Ensuring data integrity and availability in case of system failures

Benefits

The benefits of this technology include:

• Streamlined backup processes
• Improved data protection and recovery capabilities
• Enhanced system reliability and resilience

Potential Commercial Applications

A potential commercial application of this technology could be in the development and deployment of:

• Backup and disaster recovery solutions
• Virtual machine management software
• Data protection services for cloud providers

Possible Prior Art

One possible prior art for this technology could be traditional backup and recovery solutions that may not be optimized for virtualized environments.

How does the data protection agent ensure data consistency during the backup process?

The abstract does not provide details on how the data protection agent maintains data consistency while backing up the application in the virtual machine.

What security measures are in place to protect the backup data during transmission to secondary storage?

The abstract does not mention any specific security protocols or measures implemented to safeguard the backup data during the transfer process.

Original Abstract Submitted

A data protection agent is installed within a virtual machine (VM). A request to freeze an application in the VM is issued to a copy service. A request for a snapshot is issued to a snapshot data mover, external to the VM. Upon receiving an identifier for the snapshot, communications are exchanged with the copy service to thaw the application, the snapshot identifier is passed to the agent thereby allowing the agent to access the snapshot and rollover data from the snapshot to secondary storage for the backup, and notification to the copy service about a success of the backup is withheld. During the rollover, listening begins for status updates concerning a progress of the rollover. Based on the status updates, the copy service is notified that the backup failed or succeeded.
