See recovery FSE recovery | HP File System Extender (FSE) specification

event log	A file that records relevant information on events happening in the FSE processes during the
(FSE event log)	operation of the FSE implementation. FSE event log, named fse.log, is located in the
	directory /var/opt/fse/log (on Linux platform) or in the directory
	%InstallPath%\var\log (on Windows platform).
explicit release	Unconditional release, started for a file or set of files on the release candidate list, specified by
	an FSE user. It is triggered with the fsefile --releasecommand and occurs regardless of
	the parameters in the release policy.
external client	An external FSE client can be hosted on any of the supported platforms. External FSE clients are
(FSE external client)	connected to the FSE server through a LAN and host HSM file systems. The client runs only the
	processes that provide functionality for managing these HSM file systems and communication
	to the major services running on the FSE server. The daemons (services) running on the client
	are: File System Event Manager, Hierarchical Storage Manager, and Service, with additional
	FSE Windows Service on Windows systems. See also ”client (FSE client)”.
Fast Recovery	File System Catalog related data, collected during migrations and used for eventual recovery of
Information (FRI)	the FSE implementation. Medium volumes that are not yet full have Fast Recovery Information
	stored on the disk in the directory /var/opt/fse/fri (on Linux platform) or in the directory
	%InstallPath%\var\fri (on Windows platform). Once medium data volumes are full
	(filled up with migrated files), Fast Recovery Information is written to the part of the medium
	volume that was reserved in advance for this kind of data. Typically, a medium is partitioned to
	have a system volume, which stores redundant copies of Fast Recovery Information from all data
	volumes on the medium.
file generation	A version in the history of a particular file on an HSM file system. Older (non-latest) file
	generations are only stored offline, as they have already been migrated to FSE media, whereas
	latest file generations can be present either online or offline, depending on the time of their last
	access and the corresponding FSE partition policies.
file split	In some situations, the amount of available space on the currently open FSE medium volume is
(FSE file split)	smaller than the amount of data in the currently migrated file. To use the remaining space on
	the open volume, FSE splits the migrated file into two or more parts, and stores each part on a
	separate volume. Such migrated file parts are called FSE file splits.
File System Catalog	A database, which consists of the Data Location Catalog (DLC) and Name Space Catalog
(FSC)	(NSC). The Data Location Catalog (DLC) contains information about location of files on the FSE
	media (full history). The Name Space Catalog (NSC) contains metadata of files on an HSM file
	system (the last generation metadata). Each FSE partition has its own File System Catalog. See
	also ”Data Location Catalog (DLC)” and ”Name Space Catalog (NSC)”.
File System Catalog	A file which contains transaction information for the File System Catalog. It is designed to
journal	increase the catalog robustness. FSC journals contain information about already applied and
	pending catalog transactions. File System Catalog journals are located in the directory
	/var/opt/fse/part/PartitionName/fsc/journal (on Linux platform) or in the
	directory %InstallPath%\var\part\PartitionName\fsc\journal (on Windows
	platform).

recovery job
file system event	A creation or modification of a file on an HSM file system, detected and handled by the FSE
	software. The following operations are identified as relevant file-system events for FSE: create,
	rename, move, delete, read of contents, change of contents (write, truncate) and change of file
	attributes (ownership, permissions, and so on).

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.
