Cloud backup for photos

I use the synology photos app on my iPhone so that every time when I take a photo or video from my phone it automatically backs up to my NAS via the synology photo app .

I would like to know what people recommend doing for a cloud backup solution for just the photos however I want to retain the original meta data for my photos and not have it all overwritten to the date the photos were uploaded ?

Ps I don’t want to use AWS s3 storage , too complicated for a simple task . Is synology c2 storage worth it ?
