Prerequisites

Common

•On the consolidated FSE system or FSE server, Firebird SuperServer must be running.

•Processes on all hosts of the FSE implementation must be stopped.

For stopping FSE processes on a particular host, locally run the fse --stopcommand. Note that the processes must be stopped on the external FSE clients first.

•Backup FSE medium that contains the desired backup image must be loaded into an FSE drive.

Since all FSE processes are stopped, to fulfill this prerequisite, you need to use the FSE tool fse_la to load the medium into the drive. For more information, see chapter ”Troubleshooting”, section ”FSE troubleshooting tools” on page 274.

Linux specific

•You have to be logged on to the system as root in order to perform the restore steps.

•Logical volumes on all the clients that you are going to restore must have the same names, file system types, and sizes as they did at the time of backup. These logical volumes are fsevar, fsepart, and fsediskbuf (the latter only on the consolidated FSE system or FSE server).

•Logical volumes fsevar, fsepart, and fsediskbuf should be mounted on the appropriate mount points in the FSE directory structure.

For more information, see appendix ”Directory layout” on page 291.

Windows specific

•You need administrative privileges to perform the restore tasks. These privileges are granted only if you are either locally logged to the system as Administrator (recommended) or using a remote access software that supports logging in with the real Administrator account. The Windows native Remote Desktop tool, for example, may be unsuitable for these tasks, since it uses a different Administrator account when logging in remotely.

The restore process

The following steps describe FSE restore process. Steps of the process are the same on all supported platforms:

1.According to the specified restore source, one or more backup images are copied from disk (local or remote disk volume or share) or tape (FSE medium in the backup FSE media pool) and temporarily stored in FSE disk buffer.

NOTE: This step may be long lasting and may take considerable amount of time if backup image on tape is chosen as the restore source.

2.This step depends on whether restore or retrieval of backup images is requested:

•If restore is requested, the backup image file is uncompressed and contents of the archive are extracted to the appropriate locations on the FSE server.

•If retrieval of backup images is requested, depending on the options specified in the command line, backup image files are either preserved in FSE disk buffer or moved to the specified directory.

After the restore, you need to perform mandatory post-restore steps. For details, see section ”Post-restoresteps” on page 235.

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.
