vrmlogger-backlog - file too big / missing data after splitting the file

Good day

We retrieved a backlog file of 1.12GB original file, see here: https://www.dropbox.com/s/tk9lnq1lh91cntb/vrmlogger-backlog.sqlite3?dl=0 , the zip file here: https://www.dropbox.com/s/j92anffr9993n3j/vrmlogger-backlog.sqlite3.zip?dl=0 (82.7MB)

We were splitting this file and imported 2 files, but are missing the very important battery SOC data.



Here the 2 files after the split:

- https://www.dropbox.com/s/kkalkyxwoa5qyq7/vrmlogger-backlog_olddata.zip?dl=0

- https://www.dropbox.com/s/l4j2nelsmfckzns/vrmlogger-backlog.zip?dl=0

Thanks for any advise and support.

How did you split the file? I have split a file with "Split to volumes bytes" in 7-zip but VRM tells me it is not a .sqlite3 format when I upload. My file is over 2GB

I also have a 1.9GB logger data file, that once compressed is still over the 64MB threshold. I am interested to know how the file can be divided into 2.

That might be working as intended. Full VRM data is only stored for 6 months. Consumption and Production summery data is stored for 5 years, but that doesn't include battery states of charge.

See the section in the VRM FAQ here - How long is the data stored for?

I have some ideas for how this behaviour could be improved myself, and have been thinking about it for a while.

Feel free to express your experience into the editable google doc so we can work together to make it better.

You may also wish to try using the database conversion feature of VictronConnect for Windows or Mac.

Though I have never used it for a dataset so big, so please let me know if it works. It might take an hour of computer thinking 💭

I have problems on my CerboGX. I noticed that one file occupied the entire memory. Is that normal?
