How Time Machine Works, How to back up and restore your Mac using Time Machine
Time Machine operates by creating incremental backups of your data. It does not copy the entire contents of your hard drive every time a backup is performed. Instead, it only copies new or modified files, making the backup process efficient and time-saving.Time Machine stores backups on an external drive, such as a hard drive, SSD, or network volume.
This ensures that your backups are stored separately from your main hard drive, protecting them from accidental deletion or damage.
“Time Machine backs up your entire Mac, including your system files, applications, user accounts, and documents.”
Setting Up Time Machine
Setting up Time Machine is easy and straightforward. You’ll need an external drive to store your backups, and Time Machine will automatically handle the rest.
