HP StoreOnce Backup - Manual (Page 156)

14 Configuration save and restore process
StoreOnce appliances enable creation of a backup of device configuration settings in the form of
a file that can be retrieved from the appliance and stored on the user’s PC for possible use in the
future.
The configuration backup file may be used to quickly configure a replacement or repaired StoreOnce
appliance in the unlikely event that the appliance fails and all data and configuration details are
lost.
The file would be used after a system is repaired or replaced in one of the following cases:
•
A failure of the appliance operating system on both nodes in a couplet has occurred and
configuration details and data are lost for the couplet.
•
A failure of the appliance operating system on all nodes in a cluster has occurred and
configuration details and data are lost for the cluster.
The configuration save and restore process is managed via the StoreOnce CLI and an SFTP client
is required to download or upload the saved configuration file.
CAUTION: The configuration save and restore process does not include encryption key store
data. If using this feature, separate StoreOnce CLI commands should be used to back up the
encryption key store and store it safely in an offline location. Use the original key store to access
encrypted key store data after a restore.
Configuration file
The configuration file consists of two parts:
1. A set of instructions in the form of a text file for the user to manually restore some of the network
and device management configuration settings that cannot be automatically restored.
2. A zip file containing StoreOnce device configuration settings that automatically restore
configuration settings that have been created for StoreOnce VTL, NAS, Catalyst, Replication
and housekeeping functions.
IMPORTANT: If settings in the text file need to be restored, the manual restore should always be
carried out before the automatic restore.
When should a configuration file be generated?
A configuration file should be generated and copied from the StoreOnce appliance whenever a
change in configuration is made to the appliance, in order to ensure that if a recovery is required
then the latest data is available, for example:
•
After changing network settings
•
After creating virtual tape libraries, NAS shares or StoreOnce catalyst stores
•
After modifying replication settings
•
After updating software
IMPORTANT: Configuration files saved on older versions of the software are not usable after the
software is updated.
Contents of the configuration text file
The configuration text file contains information required to reconfigure some appliance settings; it
details the commands that need to be sent via the StoreOnce CLI interface or the steps required in
the GUI to apply the settings.
