3, 2, 1 Backup!

I learned about the 3, 2, 1 backup method. It basicly were you have an inportant file and you have three copies of it and two or stored on to close locations, and the last on something like google drive. I am applying this to my Proxmox VE server by setting my VM’s to my NAS and there will be three copies of them (3). Then I will keep one copy on the NAS then have another copy on my computer (2). The last copy will go on google Drive (3). If you are trying to make a backup plan I would use the 3, 2, 1 method.
