How to backup mac with time machine

Backing up the hard drive to a Mac with Time Machine

Once the hard disk on the Mac is damaged, all data is lost irrevocably. This is particularly annoying if the data is nowhere else secured. Family and vacation photos, the CV, important documents, music, and films – losing it all would be very bitter. To avoid this scenario becoming an unsightly reality, backups of the data should regularly be made.

With Time Machine, Apple delivers a built-in backup system as it were. If you connect an external drive to the computer and assign this time machine, the Mac automatically backs up each time the hard disk is connected. Folders or the like do not have to create additional. All files stored on the computer are automatically saved. Time Machine is designed to create a copy of each file on your computer.

This is a backup with Time Machine

When connecting an external hard disk for the first time, the Mac should normally ask if a backup should be created with Time Machine. Then you can permanently set this hard disk as a backup volume. The setting is also possible manually. Step by step this works then so …

  1. Time Machine can be selected via “System Settings.”
  2. In the “Time Machine” system settings, click on “Select volume …”.
  3. Select the disk on which the backups should be stored.
  4. The backups are then stored in a dated folder as a copy on the external hard drive.

Also, it is possible to select which objects are not to be saved via “Options …” and whether the backup should also be made during the battery operation. It is also possible to make a notification before deleting old backups.

Just a few tips

  • In its basic setting, Time Machine keeps a lot of data, in very short time intervals, which do not have to be stored. This means, of course, a large data volume, which must constantly be copied. This can unnecessarily cost a lot of computing power.
  • To change the intervals for backups, there are several additional tools such as TimeMachineSheduler or TimeMachineEditor.
  • Also, the speed of the backups can be speeded up by the above-mentioned exclusion of specific folders. For example, programs (applications) usually still exist on CDs or as download links. Even download folders themselves, are usually temporary and therefore do not have to be stored permanently as a backup. Just like the folder for the dropbox – its data is stored on a server, not on the hard disk.
