Section 3. Installation, Operation and Backup Procedures
3.2.2.1 Performing a Backup
RTDAQ provides a simple way to back up the network map, the RTDAQ data
cache, and the initialization files for the main application. The network map
will restore all settings and data collection pointers for the dataloggers and
other devices in the network. The data cache is the binary database which
contains the collected data from the datalogger. Initialization files store settings
such as window size and position, configuration of the data display, etc.
The *.INI files backed up in the RTDAQ backup procedure are
those found in the C:\Campbellsci\RTDAQ\sys\inifiles folder
only. Other *.INI files such as those for Short Cut,
CardConvert, Split and the CRBasic Editor are not a part of the
backup. NOTE
From RTDAQ’s menu, choose Network | Backup/Restore Network, and then
press Backup.
The backup file is named RTDAQ.bkp and is stored in the
C:\CampbellSci\RTDAQ directory (if you installed RTDAQ using the default
directory structure). You can, however, provide a different file name if
desired.
3.2.2.2 Restoring the Network from a Backup File
To restore a network from a backup file, choose Network | Backup/Restore
Network. Select the *.bkp file that contains the network configuration you
want to restore, and press Restore. Note that this process DOES NOT append
to the existing network — the existing network will be overwritten when the
restore is performed.
3.2.3 Loss of Computer Power
The RTDAQ communications server writes to several files in the \SYS
directory during normal operations. The most critical files are the data cache
table files and the network configuration files. The data cache files contain all
of the data that has been collected from the dataloggers by the RTDAQ server.
These files are kept open (or active) as long as data is being stored to the file.
The configuration files contain information about each device in the datalogger
network, including device settings, and other parameters. These files are
written to frequently to make sure that they reflect the current state and
configuration of each device. The configuration files are only opened as
needed.
If computer system power is lost while the RTDAQ server is writing data to
the active files, the files can become corrupted, making the files inaccessible to
the server. While loss of power won’t always cause a file problem, having
files backed up as described above will allow you to recover more effectively
if a problem occurs. If a file does get corrupted, all of the server’s working
files need to be restored from a backup file to maintain synchronization with
the server state.
