* A timely recovery from deletion or corruption of configuration files (e.g., ``node.conf``, ``node-info`` files, etc.), database drivers, CorDapps binaries and configuration, and certificate directories, provided backups are available to restore from.
.. warning:: Private keys used to sign transactions should be preserved with the utmost care. The recommendation is to keep at least two separate copies on a storage not connected to the Internet.
Checking node version and installed CorDapps
--------------------------------------------
A ``nodeDiagnosticInfo`` RPC call can be made to obtain version information about the Corda platform running on the node. The returned ``NodeDiagnosticInfo`` object also includes information about the CorDapps installed on the node.
The RPC call is also available as the ``run nodeDiagnosticInfo`` command executable from the Corda shell that can be accessed via the local terminal, SSH, or as the standalone shell.
Example
+++++++
Here is a sample output displayed by the ``run nodeDiagnosticInfo`` command executed from the Corda shell:
