SyncBack, Macrium Reflect & Arq.
My PC is not worthy to be backed up, but I have used Paragon Backup & Recovery Community Edition just in case.
The community edition is free to use for non-commercial purposes.
I don’t currently have a PC but I have used Veeam Agent for years to back up several machines, including my parents’ machines where I wanted a product that I could set up, let it run in the background with no notifications to confuse them, and forget about it unless something’s wrong.
Community edition is also free so perhaps worth checking out.
BackBlaze for off-site.
