Thanks a lot!!:heart_eyes::heart_eyes: Curiously, MySQL [is still the recommended database](https://docs.nextcloud.com/server/20/admin_manual/configuration_database/linux_database_configuration.html)...?!

Except some warnings to prevent, they look stable (and are being used in an official app).

Fortunately, Nextcloud has taken care of that migration use case! https://www.techandme.se/we-migrated-to-postgresql/ https://docs.nextcloud.com/server/13/admin_manual/configuration_database/db_conversion.html

We could put up a dirty fix in the backup script, but that's not satisfying... Any other opinion on this @YunoHost-Apps/apps-group ? EDIT: Oops, that latter...

Yes, but what are relevant use cases? Here there is a problem somewhere that makes that file disappear... is there any other potential problem that could be hidden behind this...?

Hi, Regarding the redis part, it has already been implemented here https://github.com/YunoHost-Apps/nextcloud_ynh/commit/57c8122f4a441aba5aab6f041157399904d1de9e For the database part, can the tuning be restricted to the app's database? If not, it would be...
