Hyper Backup is native to Synology and
offers a variety of backup models, (Rsync,
Rsync single copy, WebDAV, etc.) to a
variety of local and cloud services.
Arq is a pretty sophisticated backup program
which will also let you target local and cloud
services, and like Synology also offer their own
cloud.
Yes, both do version control.
How creative does your backup process need
to be? Backup should be “set and forget” to
raise the odds of it getting done. 
IMHO If you have a Synology use Hyper Backup
