I am dropping this here in case it helps anyone accomplish what I was after for our DokuWiki documentation site.
This will give you a fully automated offsite sync of all pages and media (utilizing the gdrive client by prasmussen). I have also wrote a script that utilizes the DW2PDF plugin (by Andreas Gohr) to create an automated full export of every page in PDF format, organized in the same folder structure as the wiki site itself. The script has built in event notifications by email and error handling (to an extent).
The GitHub repository has a full walkthrough on setting it all up:
GitHub - dokuwiki-rclone-sync+pdf-export
Any questions/feedback/suggestions are welcome.
Switched to using rclone for sync instead of gdrive.
