AUTOMATED BACKUP AND RESTORE OF A DISK GROUP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240248811 titled 'AUTOMATED BACKUP AND RESTORE OF A DISK GROUP
Simplified Explanation: The patent application describes a method for restoring a clustered database with multiple nodes, each having a database from a failed storage device. The process involves receiving a request to restore a backup image of a failed shared storage device associated with the clustered database to a specific time, conducting preflight checks, terminating the restore if any checklist process fails, and completing the restore by creating flashcopies, mapping them to each node, mounting them as diskgroups, and switching the clustered database to run from the diskgroup.
Key Features and Innovation:
- Restoring a clustered database with multiple nodes from a failed storage device.
- Preflight checks to ensure the restore process is successful.
- Creation of flashcopies associated with the backup image.
- Mapping flashcopies to each node and mounting them as diskgroups.
- Switching the clustered database to run from the diskgroup.
Potential Applications: This technology can be applied in data recovery and disaster recovery scenarios where clustered databases need to be restored from failed storage devices.
Problems Solved: This technology addresses the challenge of efficiently restoring a clustered database with multiple nodes from a failed storage device while ensuring the integrity of the data.
Benefits:
- Improved data recovery process for clustered databases.
- Enhanced reliability and efficiency in restoring databases from failed storage devices.
- Minimized downtime and data loss in case of storage device failures.
Commercial Applications: The technology can be utilized by data centers, cloud service providers, and enterprises with large-scale database systems to ensure quick and reliable recovery in case of storage device failures.
Prior Art: Further research can be conducted on existing technologies related to data recovery and database restoration in clustered environments to identify any prior art relevant to this innovation.
Frequently Updated Research: Stay updated on advancements in data recovery technologies, storage systems, and database management solutions to enhance the efficiency and effectiveness of clustered database restoration processes.
Questions about Clustered Database Restoration: 1. What are the key steps involved in restoring a clustered database from a failed storage device? 2. How does the use of flashcopies improve the efficiency of database restoration in clustered environments?
Original Abstract Submitted
restoring a clustered database having a plurality of nodes each having database from a failed storage device by receiving a request to restore a backup image of a failed shared storage device associated with the clustered database to a time; performing a preflight check including at least one checklist process; terminating the restore when any checklist process fails; when each checklist process succeeds completing the restore by creating at least one flashcopy associated with the backup image, mapping to each of the plurality of nodes an associated portion of the at least one flashcopy, mounting the at least one flashcopy to the node as a diskgroup, and switching the clustered database to run from the diskgroup.
