Restoring old data to new Cumulus

[krimatic]

Hi! Recently I had a HDD failure so I using new computer for Cumulus. I have logs since Mar 2015 so I copied all old logs to new data folder on new computer. But my new Cumulus dont see old datas, so I cant see old extremes etc. What file I have to change that Cumulus include also old logs? I tried to find something about on wiki web page but unfortunatelly I didnt find anything.

Hi,
Do you mean the original Cumulus (Cumulus1) on a new computer or the newer CumulusMX (CMX) latest version on a new computer?
If the newer CumulusMX, in the Station settings > General Settings > Advanced Options > Records Began Date and enter when your records began.

Enjoy,
Paul

Hi Paul,
I have same version of Cumulus (Cumulus 1) on new computer. And I copied all old monthly logs to data folder but current installation can see only datas from instalation date, not before. So, for example, records are only from last month, not since 2015 when logs exists

Hi,
From the View tab > Data logs > Load do all the data files appear for selection or only from last month?
From Edit tab > Dayfile do all the daily data lines appear or only from last month?

Do you also have WeatherlinkPC program, and if so does the data appear in it?

Enjoy,
Paul

Hi Paul,
View tab > Data logs > Load shows all logs ever recorded as I copied logs from old HDD to Cumulus data folder but from Edit tab > Dayfile records begin Dec 4th 2023 (day of installation of Cumulus to new computer.

I dont have Weatherlink, I use LaCrosse 2307

If I understand correctly all the old Cumulus\data files were copied to the new \Cumulus, including all the monthly log files, dayfile.txt, and the .ini files - month, monthlyalltime, today, year, yesterday. Did you also copy the original \Cumulus\cumulus.ini settings File?

CumulusMX has a station setting where you enter the date when your records began, and this is written to the Cumulus.ini settings file. Cumulus1 does not have such a setting in the dashboard but there is a "StartDate=m/dd/yy" entry in the \Cumulus\cumulus.ini file [Station} section. If you have all the old |data files in your new \Cumulus\data then I suggest, with Cumulus stopped, you edit the cumulus.ini file and change the StartDate={when your data started} and then restart Cumulus. Hopefully this will then display everything as before.

Unfortunately Cumulus1 does not have a tool to create missing dayfile.txt data from the monthly log files, which is one of the newer features of CumulusMX.

Enjoy,
Paul

In fact I copied only mothlylogs txt and expected that Cumulus will do rest. So I restored all files from data folder and also restored old cumulus.ini file.
No I can get extremes even from before reinstalation but graps dont see old data,same as "view - this period" dont show any data if I pick some period from old Cumulus. Is there some trick how to force Cumulus to understand that older data exists?

Paul told you what to do

Cumulus1 does not have such a setting in the dashboard but there is a "StartDate=m/dd/yy" entry in the \Cumulus\cumulus.ini file [Station} section.

No, no trick, it should work if your install and settings are correct, and your data is valid.
Re graphs, go to > Configuration > Display and there click on Help, and read the text on Graphs and see if that is helpful.
Do the same in > View >Graphs
Can you do a screen capture and attach to a post of your > View > Select-A-Graph, and also > View > This period

If I recall correctly you are talking about Cumulus 1.9.4 build 1099, and can you also confirm you have installed the Patch to fix the year 2020 limit.

Enjoy,
Paul
