Photographers and families come to mind when using this. Have just upgraded to DSM7 to use Synology Photos, I'm having issues uploading videos from Android app. At the time of writing, Synology Photos has a 3.
Synology photos upload I've set it to upload all existing photos and videos, I think it's done all the photos, but it's having a hard time doing the video, they are large files 1gb+ and only seeems to.
