This default setup should not be used in a serious production environment but the logs and
the actual database should reside in separate file systems, preferably on separate physical
devices. Any database write shall be recorded both to the logs and the actual database table

system. High-end disk array storage devices may not suffer from this but as a rule-of-thumb it
is always a good idea to separate logs and the actual database.
The script continues:
Do you want to create databases now [Y/n]? <enter>

The script continues and the database creation takes several minutes:
7SIGNAL creating management database...
7SIGNAL creating measurement database...
7SIGNAL creating security database...
Do you want to change the default database logging method (circular
logging) to infinite archival logging [y/N]? <enter>

design and practically endless storage device. The instructions for moving to infinite archival
logging are in the Carat User Manual among other detailed backup process design issues.
