It is important to back up your data to avoid the risk of data loss during device reset. And once you get a new device, you can easily restore all your data with just a few clicks. Here are different ways to back up your Mac:

Time Machine is a built-in backup feature that can automatically back up all your personal data on your Mac. However, it does require external storage devices such as USB, FireWire, and Thunderbolt ports.

Save files to iCloud and iCloud Drive

iCloud is Apple’s unique cloud storage and computing service that allows you to store and sync all your photos, files, music, notes, contacts, and more across all Apple devices.

This service works throughout the Apple ecosystem, so if you have an iPhone or iPad, you can also back up your data from your iPhone or iPad on iCloud. Note that each Apple ID has only 5GB of free iCloud space. You need to upgrade your iCloud account for higher storage capacity.

External storage

iCloud seems to be the best option for Apple users, but you can also use other cloud-based storage devices to store your data online.

However, like iCloud, backups performed through external cloud storage are significantly more limited than Time Machine backups, which can store all your Mac’s data.

2. Migrate files to new Mac

If you’ve upgraded to a new Mac, you can use the Migration Assistant to migrate your data from your old Mac to your new MacBook. This includes all settings, apps, user accounts, and documents.

The process depends on the OS on which your Mac is running. However, you usually need to connect both devices to a power source and connect them to the same WIFI network or cable.
