Section 3. Installation, Operation and Backup Procedures
The following figure shows the typical working directories for RTDAQ if the
default options were selected during installation:

3.2.2 Backing up the Network Map and Data Files
As with any computer system that contains important information, the data
stored in the RTDAQ working directory should be backed up to a secure
archive on a regular basis. This is a prudent measure in case the hard disk
crashes or the computer suffers some other hardware failure that prevents
access to the stored data on the disk.
The maximum interval for backing up data files collected from dataloggers
depends primarily on the amount of data maintained in the datalogger memory.
The datalogger’s data tables are typically configured as ring memory. Records
will be stored to a table until the number of records reaches a predefined size,
and then each new record will overwrite the oldest record. If the data is
backed up more often than the oldest records in the datalogger are overwritten,
a complete data record can still be maintained by restoring the data from the
backup and then re-collecting the newest records from the datalogger.
