    Requirements for backing up with Time Machine

    First of all, you should know that in order for your Mac to make a backup copy to an external device, it must have a specific file format compatible with the operating system.

    Time Machine does not allow backups to iOS devices or hard drives formatted for Windows . If the disk you have is not using the correct format, Time Machine will ask you to erase it when you connect it to your Mac.

    For this reason, we recommend using more suitable devices to make backup copies with Time Machine on Mac, among these we can mention USB Thunderbolt or FireWire drives, an external drive connected to an AirPort Extreme base, an AirPort Time Capsule or any other Network Attached Storage supported by Time Machine via SMB.

    With these devices you will have the guarantee that your backup is done correctly and you can use it without difficulty wherever you want to restore it.

    When you connect your storage device to your Mac computer, you may automatically see a dialog asking if you want to use it for Time Machine backup.

    In this case, select the "Encrypt Copy Disc" option, it is the most recommended. Then, click the "Use this disk" button. In case the drive is not recognized automatically, below we explain how to enter Time Machine, manually select the disk and configure the backup according to your preferences.
