I use a Synology NAS too. It's already 5 year old but working fine, still getting updates regularly. The Hyper Backup is a wonderful tool (comes with Synology) that you can use to create multiple backup strategy, to another portable hdd, various cloud providers, any host with rsync etc, with or without backup version and rotation. The user experience is pretty neat.
