How it works?

You need to ensure that the prerequisites are met and consider the backup process, before you start backing up the FSE implementation.

Prerequisites

Common

•If tape will be used as a backup destination, backup FSE media pool and backup FSE media have to be configured.

For more information on the configuration procedures, see section ”Backup media management” on page 223.

Linux specific

•All FSE components that will be backed up, except the global configuration files, must reside on LVM logical volumes.

•Parameters in the FSE backup configuration file should be set appropriately.

For details, see section ”Backup configuration file on Linux platform” on page 222 or the fsebackup man page.

•The dm-snapshotmodule must be loaded. SUSE Linux specific

For information on how to load the dm-snapshotmodule and configure its automatic loading at system startup, see section ”Loading the dm-snapshot module on SUSE Linux operating system” on page 222.

Windows 2000 Server specific

•StorageCraft Volume Snapshot must be installed on the system. Note that snapshots are not visible as drive letters and are available only to the fsebackup command.

Backup configuration file on Linux platform

FSE backup configuration template and FSE backup configuration file are named backup.cfg. FSE backup configuration template is located in the directory /opt/fse/newconfig. FSE backup configuration file is located in the directory /etc/opt/fse.

In the FSE backup configuration file, you can only configure the parameter SNAPSHOT_PCT, which represents percentage of the ordinary logical volume size that is reserved for the LVM snapshot. SNAPSHOT_PCT defaults to ten percent (10 %). You should increase this value if there is high traffic expected on the HSM file system with many changes to the file system contents while FSE backup process is in progress.

Loading the dm-snapshot module on SUSE Linux operating system

On the supported SUSE Linux operating system, the dm-snapshotmodule, which is required for the FSE backup, is not loaded automatically.

To load the module, invoke the following command:

# modprobe dm-snapshot

To configure automatic loading of the module at subsequent system startups, add the string dm-snapshotto the variable MODULES_LOADED_ON_BOOT in the file /etc/sysconfig/kernel, like shown in the following example:

## Type:

string

## ServiceRestart:

boot.loadmodules

#

 

#This variable contains the list of modules to be loaded

#once the main filesystem is active

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.
