I want to degoogle and this is one of the last steps. The free versions of other services provide too little storage so I was wondering if I can make a cloud using my raspberry pi
Nextcloud
This is what I run, but I run it on my media center which is real full workstation hardware since it runs media center stuff, plus all of my home server stuff. Nice thing about next cloud is you can use it to sync contacts, calendars, todos, Joplin, as well as just the box type storage application.
I would vote for syncthing as it can have better support if you need syncing across work firewalls. Also allows device-to-device sync, not just server-device. It’s a cool federated solution (like lemmy!).
Seafile. Nextcloud runs like ass, particularly on low powered devices like the Pi.
Nextcloud. Do not forget to backup your data and sql db. Use mariadb or postgresql on initial setup and configure php-fpm, opcache and other tunings you may refer to documentation
