Restore lost data

InfluxDB 2

Hi guys,

I have quite a tricky problem with my influxdb.
I’m running the influxdb as a docker on my Synology NAS system.
Because if the retention period, I just lost 1 month of data which I would like to get back.
As I have a backup of the local files of the docker (data and config folders) I would like to restore the lost month of data out of that backup.

Is that even possible and if yes, how?

  1. How can I access the data of the local file backup?
  2. How can I extract just the lost months data?
  3. How can I join the lost month to the current live data?
