i’m new to influxdb and the last few days i try to understand how influxdb is working behind the scenes. I think i got a rough understanding about this, but a few things are not clear to me and i didn’t found an answer on the internet.
I’m using influxdb 1.8 and playing around a little bit with backup and restore. In the documentation there is a Note: " Note:
backup ignores WAL files and in-memory cache data.".
As i read so far, influxdb write’s data to the WAL-Files and after a given time or a specific amount of space the data of the WAL-Files is written to TSM-Files.
Does this mean, if i’m running a Backup via “influxd backup”, that all data that is currently stored in the WAL-Files is lost?
