Backups on or by the computer might protect you from disk failures, but are useless in case of fire or theft.
With ransomware and rarely-used files, it's also important to have generations of backups, in case an infection clobbers your recent backups of files before you detect the infection.
Yes, and not on the same disk! I have three USB disks, each of which is capable of holding half a dozen backups. Disk 1 has slots 11-19, disk 2 21-29 and disk 3 31-39. Backups are done in theory to 11, 21, 31, 12, 22, 32 ..., though in practice I may dump extra backups on the same disk if I'm doing configuration or upgrade work.
