Missing data points with Backup & Restore

Hi I want to migrate date from one InfluxDB 2.0.2 to another InfluxDB 2.0.4, but with backup & restore, some data points are missing:

How I create the backup: influx backup <FILENAME>
How I restore from backup: influx restore --full <FILENAME>

Source (Backup):

Destination (Restore):

I noticed only the following warn messages on the source by creating the backup:

I don’t found any other errors or warn logs.

Why are some data missing?
