Use the Archive Database tool (Settings icon –> Database Settings –> Archive Database) to manually generate a local archive of the current database. (The database can also be automatically archived; see Remote Config Archive for more information.)
To prevent loss of data in the event of an appliance hardware failure, make database archive copies on a regular basis and store them in a safe place. If no recent database archive exists and NetMRI has an unrecoverable error, then all data will be lost.
By default, NetMRI automatically generates a database archive file once every week, as specified in Settings icon –> Database Settings –> Maintenance.
Depending on the size of the database, archiving may take a few minutes, because the entire database is copied to a disk file and compressed. During archiving, NetMRI automatically disables data collection, to maintain a consistent database snapshot. Data collection is re-enabled after archiving is complete.
...
Under some circumstances, you may need to restore from a database file generated from another NetMRI instance to the current NetMRI system (from one NetMRI Collector system to another one, for example). in such cases, the NetMRI Database looks for a locally generated database to restore, using the file naming format of the current NetMRI instance.
If a database is present in the local archive directory that originates from a remote NetMRI using a different file naming format, the restore will fail to find the local DB that it is seeking by default, and also will not access the 'outside' database archive file you are trying to restore from, displaying an error message.
The restore CLI command supports the use of database archives originating from another system.
The *.tgz database file must be transferred to the file system in the current NetMRI instance before execution. An example:
restore <filename>, where <filename> is the archived file name without the extension.tgz

The Scheduled Archive page (Settings icon –> Database Settings –> Scheduled Archive) controls automatic archiving and copying of the NetMRI network database. (The database can also be manually archived; see the Database Archiving Functions topic for more information.)
When enabled, the automatic process creates an archive of the NetMRI network database and copies it to one or two servers that support SCP, or to another NetMRI system.
To configure automatic network database archiving, do the following:
...
The Remote Config Archive page (Settings icon –> Notifications –> Background Tasks) provides a read-only display to monitor selected NetMRI internal background tasks that may occupy significant periods of time, and are thus organized in the system to run in the background while NetMRI operates normally.
Key values to check here include the Progress % field, which indicates the amount by which each background task has completed, and the Created field, which indicates the creator of the task. In many cases, the value shown here will be "System."

The Remote Config Archive page (Settings icon –> Database Settings –> Remote Config Archive) controls automatic archiving and copying of the NetMRI configurations. Also check Data Retention settings in the Data Retention topic, as they have significant influence on the time periods between data archiving events for specific data sets in NetMRI.
When enabled, this automatic process creates an archive of the configurations and copies it to one or two servers that support SCP.
To configure automatic configuration archiving, do the following:
- Select the archiving Frequency (Daily or Weekly).
- Select the Hour to Start and Minute to Start. For weekly archiving, also select the Day of Week.
- For each backup location, enter the Backup Destination, Username, Password and Backup Directory.
- For transferring to another NetMRI appliance, enter admin as the Username and enter Backup as the Backup Directory.
- To date-stamp the directory name: Check the Include date in directory name option.
- To test the configuration: Click , click Test.
- If the test is successful. , click Update.

Use the Maintenance page (Settings icon –> Database Settings –> Maintenance) to change settings for weekly database maintenance. The maintenance task can be configured to start at any time during the week, to be coordinated with other maintenance activities performed by your organization.
Data collection is automatically suspended during maintenance. During that time, the NetMRI browser interface will also be disabled, displaying only a status message indicating that maintenance is being performed.
When archiving completes at the end of each maintenance cycle, the NetMRI appliance reboots to restart all processes and then resumes data collection.

You may also target troubleshooting information to specific devices in the managed network, including the ability to perform an SNMP Walk and SNMP debugging, and to run a discovery diagnostic on the specified network device. You may specify one device or up to three device IP addresses for this task.
Support bundle data includes such things as NetMRI configuration and performance data, device identification database, and a significant collection of appliance debugging log files. Such data is used primarily when troubleshooting specific problems reported by customers. A support bundle may also be requested from time to time by Infoblox Technical Support staff to improve NetMRI's discovery and analysis capabilities, by searching for new device types and unusual processing situations. In all cases, send a support bundle only when requested to do so by Infoblox Technical Support staff. You may also receive instructions regarding the types of debugging logs to select for the support bundle.
The Advanced Support Page provides the following information about active and resolved cases:
...
- Use the NetMRI ping/traceroute tool via the browser interface (Tools–>Device–>Ping/Traceroute), or the ping command via the Administrative Shell, to verify that NetMRI can reach the Infoblox server bloxdrop.infoblox.com on the Internet.
- Use the NetMRI ping/traceroute tool via the browser interface, or the traceroute command via the Administrative Shell, to verify that the appliance can reach bloxdrop.infoblox.com on the Internet.
- Verify that your firewall rules allow NetMRI to make an outbound SSH connection (TCP port 22) to bloxdrop.infoblox.com.

The Storage Management page (Settings icon –> Database Settings –> Storage Management) lists the active disk partitions operating in the NetMRI system.
To add more storage to the NetMRI appliance, use the provisiondisk command. See the Shell Commands topic for more information. After executing provisiondisk and setting up the storage volume, its information appears on this page.
