Yes, I follow the 3-2-1 backup rule
1st copy is my working data
2nd copy is to an external HDD
3rd copy is offsite to a cloud site
My backup copies are incremental, using a backup service (Arq)
I also have device backup, with my data auto-sync’d between devices (Mac and iPad)
I’m not a Windows user but my data is sync’d between two different devices
If/When one device fails, I fall back to the other device
Also, my data is backed up to the cloud
