The value of tmnxSysRollbackLocation specifies the destination filepath
or file-URL where the current running configuration information
will be saved when tmnxSysRollbackSave is set to 'doAction'. If
the value of tmnxSysRollbackLocation is an empty string the system will
attempt to store the file in the best available location locally,
for example compact flash 1 or 2 if either is present.
