backed up have to reside on LVM logical volumes (on Linux systems) or addi- tional snapshot software needs to be installed in advance (on Windows systems). This is an essential prerequisite. For details on the required snapshot software on Windows platform, see the FSE release notes.

When tape is used as backup destination, FSE backup stores backup images to tape media of the backup FSE media pool. This media pool should therefore be configured before fsebackup is run. Backup FSE media pool is an FSE me- dia pool configured with the BACKUP type and preferably one data volume on its media. Since FSE backup uses only the first data volume on each backup medium, this way you ensure that storage capacity of the backup FSE media pool is opti- mally used. For details on configuring media pools, see the fsepool man page. Note that backup FSE media must be formatted and initialized before they can be used.

Warning:

As an FSE administrator, it is your responsibility to keep track of which backup image is stored on which backup FSE medium (with tape as backup destination) or in which backup image file (with disk as backup destination). With tape as backup destination, fsebackup only checks if the backup FSE media pool is configured, and if there is enough free space on any medium in it or on the backup medium specified in the command line (if the – –mediumoption is specified). To avoid potential data loss, HP also suggests that you periodically check condition of tape media in the backup FSE media pool.

THE BACKUP PROCESS If all prerequisites are fulfilled, the backup process can begin. The process is executed by a backup job. The file backup.pid prevents two backup jobs from being run in parallel in the same FSE implementation.

The backup process performs the following steps. Each step starts only if all previous steps were successful:

1.FSE server is internally suspended. Operation of all running Partition Man- agers is temporarily blocked, in order to achieve a consistent state of all File System Catalogs (FSCs) and other entities that will be backed up.

2.Data from transaction log files of Hierarchical Storage Management Databases (HSMDBs) on the FSE clients are committed to the main

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.
