Why is Time Machine backing up everything?

Episode 1672 (40:39)

George from Victor, Montana
Apple's Time Machine

George has a Seagate external hard drive for storing his photos. But when he opens it, he sees everything from photos to files. Leo says it's likely that his Mac is using Time Machine, and it's backing up everything. You have the option to disable the backing of system files and other data. So spend some time in the settings and decide what you want to backup. Once you tell Time Machine what drive you want for backup, then it'll backup regularly. Leo also recommends enabling iCloud.
