You won’t want to do that as InfluxDB will trash your SD.
When you reboot, current persistence data will also be copied to SD and available from there on. Rebooting is not recommended, however (let alone for just this purpose) .
So the official recommendation is to setup the data safety features of openHABian (menu 50) so you have a daily backup to restore from if in need e.g. after a power loss.
PS mind the posting rules, please. Search the forum and comprehensively describe your setup in the first place i.e. before you ask.
