Duplicating media

For more information on the fsemedium command, see the FSE CLI reference.

The following table helps you determine what kind of initialization is allowed for different medium volume types identified by FSE.

Medium volume type	Types of initialization

	Regular (--init)	Forced (--init --force)

Blank (new)	YES	YES

Unknown (contains data of unknown format)	YES	YES

Tar volume	NO	YES

ECMA/ANSI volume	NO	YES

FSE volume with no valid FSE user data	NO	YES

FSE volume with FSE backup images	NO	YES

FSE volume with valid FSE user data	NO	NO

Notes

FSE medium volumes that store valid FSE user data are the volumes which:

•store some data that is referenced by the belonging File System Catalog (FSC).

•belong to an FSE media pool which is currently assigned to an FSE partition.

•have the parameter Used[%] greater than zero in the output of the command fsemedium --list--volume.

FSE medium volumes that do not store valid FSE user data are the volumes for which any of the above criteria is not met.

TIP: You can initiate formatting and initialization of a medium at once with the command fsemedium --formatBarcode --init. This command formats the medium and initializes all medium volume created on it.

You can initialize a particular medium volume on the medium with the command fsemedium --initBarcode --volumeVolumeNumber.

The FSE implementation provides an option to have multiple copies of the migrated data made automatically during a migration job. You do this by configuring several FSE media pools for one FSE partition. The number of media pools assigned to the same partition corresponds to the number of copies the files will have on FSE media. For more information, see ”Multiple copying” on page 147.

Multiple copying is favorable with regards to recall, since you are able to recall your data from any available copy. All media pools that are assigned to the same partition contain the same set of data, however, it is not guaranteed that an individual medium from a certain media pool has a corresponding medium with exactly the same data in another media pool. If you want to create an exact copy of an FSE medium for eventual replacement of the original, you must duplicate the medium.

Media duplication is usually used for data vaulting, where media duplicates are put off-site to increase data safety. It can also be useful in situations where a particular medium becomes worn out and the data on it is still valuable.

NOTE: Media duplication is not available for disk media.

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.
