Description

After the FSE restore process successfully completed, FSE processes cannot be started on the

 

consolidated FSE system or FSE server.

Explanation

The most probable cause of this problem is that some files on the consolidated FSE system or

 

FSE server were either struck by disaster or accidentally deleted, and these files were not

 

backed up during the FSE backup process.

 

Note that FSE backup images do not include files from the FSE installation which are not

 

updated during FSE operation.

 

Linux specific

 

FSE backup configuration file backup.cfg is not backed up.

Workaround

Before starting the FSE restore process, repair the FSE installation. The repair process will

 

replace corrupt or missing FSE installation files.

 

Linux specific

 

Proceed as follows:

 

1.

Repair the installed FSE software by using the rpm -Fcommand.

 

 

For details, see the FSE installation guide for Linux, chapter ”Installing FSE software”,

 

 

section ”Verifying and repairing the installed FSE software”.

 

2.

Using the fserestore command, start the FSE restore process again.

 

3.

Optionally, check and modify values in the FSE backup configuration file backup.cfg.

 

Windows specific

 

Proceed as follows:

 

1.

Repair the installed FSE software by using the repair feature of the FSE installation wizard.

 

 

For details, see the FSE installation guide for Windows, chapter ”Installing FSE software”,

 

 

section ”Verifying and repairing the installed FSE software”.

 

2.

Stop local FSE processes with the fse --stopcommand, as follows:

 

 

C:\>fse --stop

 

 

FSE Windows Service stopped.

 

3.

Using the fserestore command, start the FSE restore process again.

Description

The FSE backup process abnormally terminates with the fsebackup command reporting the

 

following errors in the terminal window:

 

ERROR: Checking backup size failed.

 

ERROR: SnapshotMgr error.

 

ERROR: Release snapshots failed: ...

 

(Windows Server 2003 specific)

Explanation

This problem occurs because the Volume Shadow Copy service automatically removed the

 

existing disk volume snapshot, in order to prevent free space on the volume from running out

 

completely. Afterwards, the backup job could not calculate total size of files that would be

 

backed up.

 

This happens in circumstances, when the volume is already almost full at the time the snapshot

 

is created, and later the I/O traffic on the volume is high.

Workaround

Free some space on disk volume that stores the directory %InstallPath%\var and start FSE

 

backup again.

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.
