RESTORE CONCEPTS

fserestore copies the backup image from the spec-

ified restore source to a local directory, and performs restore of the FSE server using data from the backup image file. The restore source can be either local or remote disk volume, remote share, or FSE medium that is loaded in an FSE drive. The restore process reverts completely the state of FSE server to the point in time when the backup image was created.

For list of entities on the FSE server that are restored with fserestore, see the fsebackup man page.

Note:

Since FSE backup images do not contain copies of user data on HSM file systems, neither copies of the belonging Hierarchical Storage Management Databases (HSMDBs), FSE restore cannot be used to recreate these FSE client components. If disaster occurs on a particular HSM file system, you can use the inherent HSM file system recovery functionality to recover from it. For more information, see the FSE user guide and the fserecover man pages.

PREREQUISITES Before starting FSE restore, verify that the following pre- requisites are met in the FSE implementation:

1.FSE is properly installed and configured. For details, see the FSE installa- tion guide for a particular platform and the FSE user guide.

2.FSE processes on all hosts in the FSE implementation are stopped. Invoke the command fse – –stopon each host to stop local FSE processes. External FSE clients should be stopped before the consolidated FSE system or FSE server.

3.If tape media will be used, FSE medium with the required backup image(s) and at least one FSE drive are available, and medium that will be used for restore is loaded in the drive.

4.If restore will be performed, all files should be removed from the directory /var/opt/fse/part (on Linux systems) or %InstallPath%\var\part (on Win- dows systems) on the FSE server host, and from all its subdirectories.

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
