For Windows and Macs I've found Backblaze to be the best there is.

Their $5 a month plan for unlimited storage makes sense if you have more than 1TB of data to store and is a set and forget tool.

If your backups will be smaller than 1TB it's much cheaper to use Backblaze B2 or Amazon S3 for storage.

You can set up an automated full system backup using scheduled jobs via either duplicity, borg, duplicati or duplicacy. All of them are great tools. I've yet to try out restic.

I am using Zoolz lifetime plan with 1TB space for backup (due to compression, it is handling about 3 TB of data), bought for about the price you have mentioned for year with Backblaze. It is working great so far. Restore takes several hours to start, but works fine. Their desktop app is nicely designed though is buggy.

Also, make full disk clones using something like Clonezilla or Macrium Reflect. That way you can return to a fully function system without the need to reinstall or re-setup everything on your system.
