I have a synology Nas at home with a 6tb storage which might suit your needs.
The photostation app backups my cellphone photos to the NAS, I also have daily glacier backups and backup to my home desktop regularly.
The only caveat is that due to security, I restricted web access to the nas storage, so that the pictures are only backed up when the cellphones are connected to my house network.
