Your question/issue is unclear… Are you seeing the actual deletion of data… or are you just thinking that is what is happening here?

I am not a developer, but to me it looks like the system is flushing the buffer data storage into the actual DB files as dictated in this server.properties command…

• Period for flushing all user DB to disk. In millis

  profile.save.worker.period=60000
  

But then that is just a guess as I am also unsure what your screenshot is of anyhow… a log file or something?

More details may be needed.

@kocalka what server version do you have?

[kocalka]

0.35.3 and before I use 0.34.0 and with same problem.

[kocalka]

what is interesting is not all data is deleted. old blue data are ok but yellow old data are deleted.

[Dmitriy]

Please try to update the server to the latest one and let us know if that helps.

[kocalka]

I updated server to 0.36.2-java8 now.
I must wait few days becouse server delete the data after few days.

blynk server again deleted history data

@kocalka On what scale data was removed? Please show your superchart settings.

P. S. Have in mind - History Graph is no longer supported. (as I see it in your screenshots).

[kocalka]

I change history graph to superchart and all scale was removed.

[kocalka]

every time when data are deleted this log message is reported
