182 Backup, restore, and recovery
Restore
Contrary to FSE backup, restoring FSE data is an interactive process. Before performing a restore, you must
know how to restore your data and be fully aware of the FSE concepts and the meaning of restore. You
need to be familiar with the FSE directory layout. For more information, see appendix ”Directory layout” on
page 239.
NOTE: FSE also provides recovery of the File System Catalog and the HSM file system as an alternative
way of recreating data to backup and restore. See the recommended ways of using FSE backup and
restore, and recovery in ”Defining your backup strategy” on page 171.
What is FSE restore?
FSE restore recreates the specified parts or the whole FSE implementation to a state equal to the one at the
time of backup. Providing that the FSE backup was performed by the fsebackup command according to
the described procedure, restore is run by the fserestore command. An FSE administrator must ensure
that the prerequisites are met and follow the restore procedure that guides the administrator through the
whole process of restoring.
Depending on what you have backed up, the following FSE components can be restored:
•FSE server
Restore of FSE configuration and databases.
Linux specific
On Linux platform, FSE configuration and databases are located in the directory /var/opt/fse.
Windows specific
On Windows platform, FSE configuration and databases are located in the directory
%InstallPath%\var.
The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults
to C:\Program Files\Hewlett-Packard\FSE.
To restore the Resource Management Database (RMDB), Firebird SuperServer must be running on the
consolidated FSE implementation or on the FSE server.
• FSE server and all FSE clients
Includes the FSE server and FSE client data.
•FSE client
Restore of the HSM file system data and file extended attributes for every configured partition. File
system data is restored using the same format that was used for backup.
Linux specific
On Linux platform, tar format is used for backup and the setfattr tool is used for restoring the
extended attributes.
Windows specific
On Windows platform, FSE backup data format (fse-arch) is used for backup.
Restore procedure
You perform a restore of FSE by running the fserestore command. The restore process requires
interactive input from the FSE administrator.
NOTE: You need to run the fserestore command on the FSE server system, regardless of the type of
data you want to restore (FSE server or FSE client).
