* Data that you want to add from another system for a period when you were not running Cumulus
* How Cumulus captures archive data if it is available for a period when Cumulus was stopped
* Derivatives that have been added since particular log files lines were stored
* Solving problems when a line was not successfully written to the daily summary log file

=How Cumulus Works=
# It tracks various extremes, and cumulative totals, by comparing the derived values against existing extremes and sums stored in various [[:Category:Ini_Files|period tracking files]]
#* You can find out about how a rogue source value can affect extreme records derived from it, and how to correct such issues on the [[Correcting_Extremes]] page.
# It periodically stores the spot (current) derived values in a collection of [[Monthly_log_files]], (and so when you move to a different device, or upgrade to a new release, then providing you copy these files to the new location you will not lose any data)
#* for MX these files include [[Standard log files]], [[Extra Sensor Files]], and [[Air_Link_Log.txt]], at time of writing
#* for Cumulus 1 these files are [[Speciallog.txt]], [[Standard log files]], and [[Extra Sensor Files]], for all version 1.9.3 and 1.9.4 releases
# At the end of each day, Cumulus logs the daily extremes or daily sums, from monitoring changes in each derived value into [[Dayfile.txt#List_of_fields_in_dayfile.txt|daily summary log]]
