PREREQUISITES FSE backup uses logical volume snapshot technology to keep FSE system’s operation almost unobstructed during the backup window. To be able for the FSE backup to use this technology, HSM file systems, FSE con- figuration and all FSE databases and system files have to reside on LVM logical volumes (on Linux systems) or special snapshot software needs to be installed (on Windows systems). This is an essential prerequisite.

FSE backup uses FSE backup media – FSE media that are assigned to a special media pool, distinguished by its BACKUP type. A backup pool should be config- ured with only one volume in order to use all the space on medium. Backup media in this pool should be formatted, but not initialized. If the backup encounters an initialized FSE medium, it will return an error. This is applied to prevent loss of data. For details on configuring an FSE backup media pool, see the fsepool man page.

IMPORTANT: It is an FSE administrator’s responsibility to dedicate correct backup media for each backup session. fsebackup does not keep record of which backup media had already been used for backup and when. It will only check if media with the specified barcodes are assigned to FSE backup media pool before proceeding. It is also suggested to keep at least two backup sets in order to ensure that you have always at least one valid backup.

THE BACKUP PROCEDURE After the prerequisites are checked and ful- filled, fsebackup first suspends the FSE system and achieves a consistent state of all File System Catalogs (FSCs) and Hierarchical Storage Management Databases (HSMDBs). It then creates snapshots of all required disk volumes (/var/opt/fse and /var/opt/fse/part on Linux and appropriate disk on Windows) before resuming the FSE system operation. Suspend and resume operations are performed using the fsebak command. Once the snapshots are successfully created the backup can continue.

All relevant data is gathered together and archived using tar tape archiving utility on Linux and proprietary FSE tool on Windows (fse–arch). It is then written to the FSE backup media in form of several archive files, separated with file marks. First archives on the medium are client specific data (HSM file system and HSMDB). This is followed by File System Catalog archives for each FSE partition, then the Configuration Database (configuration information for FSE system, FSE li- braries, FSE drives, FSE media pools and FSE partitions, the Resource Man- agement Database, Fast Recovery Information (FRI) in temporary disk files and

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.
