Save luci-statistics/collectd across reboot

It must be anyone out there that wants to save longterm stats, therefore have done this?

See also this thread which is, in essence, about the same thing (saving stats across reboots, across updates, same difference.)

I wrote a backup/restore init.d script that may help (as an alternative for external storage.)

Luci_statistics data loss after upgrade

I did that, if someone else is interested: Edit 2022-05-10: Moved from Github Gists to proper Github repository. Just change BACKUP_DIR to whatever is suitable in your situation. Flash wear wise, I feel comfortable to backup it to internal flash every 6 hours, your opinion might differ.
