It\u2019s a vital tool for musicians, pro audio engineers, and content creators. Time Machine is not only essential before you upgrade to a new version of macOS or to migrate to a new Mac; you can also use Time Machine every day to make incremental backups, so you can revert to earlier versions of most any document or app and recover your data.<\/p>\n\n\n\n<p>Here\u2019s how to create a Time Machine backup in macOS Tahoe 26.<\/p>\n\n\n\n<ul><li><strong><a href=\"#Why-Use-Time-Machine?\">Why Use Time Machine?<\/a><\/strong><\/li><li><strong><a href=\"#How-to-Back-Up-Your-Mac\">How to Back Up Your Mac<\/a><\/strong><ul><li><strong><a href=\"#Cloud-based-backup\">Cloud-based backup<\/a><\/strong><\/li><\/ul><ul><li><strong><a href=\"#Local-backup-with-Time-Machine\">Local backup with Time Machine<\/a><\/strong><\/li><\/ul><\/li><li><strong><a href=\"#How-to-Create-a-Time-Machine-backup\">How to Create a Time Machine backup<\/a><\/strong><ul><li><strong><a href=\"#What-kind-of-hard-drive-do-I-need?\">What kind of hard drive do I need?<\/a><\/strong><\/li><\/ul><ul><li><strong><a href=\"#Automatically-configure-a-Time-Machine-backup-disk\">Automatically configure a Time Machine backup disk<\/a><\/strong><\/li><\/ul><ul><li><strong><a href=\"#Manually-configure-a-Time-Machine-backup-disk\">Manually configure a Time Machine backup disk<\/a><\/strong><\/li><\/ul><ul><li><strong><a href=\"#Working-with-Time-Machine\">Working with Time Machine<\/a><\/strong><\/li><\/ul><ul><li><a href=\"#Formatting-a-Time-Machine-Disk-in-Disk-Utility\"><strong>Formatting a Time Machine Disk in Disk Utility<\/strong><\/a><\/li><\/ul><\/li><li><strong><a href=\"#Time-Machine-backup-guides-for-earlier-versions-of-macOS\">Time Machine backup guides for earlier versions of macOS<\/a><\/strong><\/li><\/ul>\n\n\n\n<h2 id=\"Why-Use-Time-Machine?\">Why Use Time Machine?<\/h2>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff5c7\"><strong>IMPORTANT:<\/strong> In everyday use, turn off Time Machine while recording and editing audio and music. Turn Time Machine back on after your session so it can continue backing up your files. For more information, see Sweetwater\u2019s <a href=\"https:\/\/www.sweetwater.com\/sweetcare\/articles\/macos-tahoe-26-audio-optimization-guide\/#Turn-off-Time-Machine,-iCloud-Drive,-Cloud-based-Storage-and-Backup-Apps\" target=\"_blank\" rel=\"noreferrer noopener\">macOS Tahoe 26 Audio Optimization Guide<\/a>.<\/p>\n\n\n\n<p>If you are ready to get set up, feel free to skip this section and go right to <strong>How to Create a Time Machine Backup<\/strong>.<\/p>\n\n\n\n<p>Time Machine provides you with a local backup of not only your data, but also the third-party apps, plug-ins and other software that you install on your Mac. The backups are made to an external hard drive connected to your Mac. Even if you use a cloud-based service such as Apple iCloud, you also need a local backup, and that\u2019s why Apple provides both iCloud and Time Machine.<\/p>\n\n\n\n<p>Because you have a local backup on an external hard drive, if something goes wrong, you can use Time Machine to restore your entire system quickly. Time Machine is also valuable for incremental file backup. You can recover individual files you have deleted, or revert a file to an earlier saved state.<\/p>\n\n\n\n<p>If you decide you need to downgrade your current macOS to an earlier version that\u2019s compatible with your Mac, you can use Time Machine to restore your data and third-party apps after downgrading.<\/p>\n\n\n\n<h2 id=\"How-to-Back-Up-Your-Mac\">How to Back Up Your Mac<\/h2>\n\n\n\n<h3 id=\"Cloud-based-backup\">Cloud-based backup<\/h3>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff5c7\"><strong>IMPORTANT:<\/strong> As with Time Machine, regardless of the backup method, you should turn off all cloud-based backup services while you are working in your DAW to prevent problems with recording and rendering audio. Follow the instructions in Sweetwater\u2019s <a href=\"https:\/\/www.sweetwater.com\/sweetcare\/articles\/macos-tahoe-26-audio-optimization-guide\/#Turn-off-Time-Machine,-iCloud-Drive,-Cloud-based-Storage-and-Backup-Apps\" target=\"_blank\" rel=\"noreferrer noopener\">macOS Tahoe 26 Audio Optimization Guide<\/a>.<\/p>\n\n\n\n<p>Cloud-based backup is useful and valuable for working with documents and data, but cloud-based services generally do not back up the third-party apps and software you installed on your Mac. Cloud-based backups are not designed to enable you to restore your entire Mac if something goes wrong. That\u2019s why you should think of using cloud-based services as complementary to Time Machine, and not as a replacement for it.<\/p>\n\n\n\n<p>Apple\u2019s cloud-based service is iCloud and iCloud Drive.<\/p>\n\n\n\n<p>In addition, there are many third-party services.<\/p>\n\n\n\n<h4>Apple iCloud Drive<\/h4>\n\n\n\n<p>Apple\u2019s iCloud, iCloud+, and iCloud Drive service lets you back up photos, documents, messages, and certain kinds of data from your Mac to Apple\u2019s servers on the internet. You can access these centrally-backed-up files on multiple Mac computers, iPhones, iPads, and even Windows PCs. You can also use iCloud to share photos and other files among family members on their devices.<\/p>\n\n\n\n<p>Learn more about iCloud\u2019s features on <a href=\"https:\/\/www.apple.com\/icloud\/\" target=\"_blank\" rel=\"noreferrer noopener\">Apple\u2019s iCloud page<\/a>.<\/p>\n\n\n\n<h4>Third-party cloud-based backup and file sharing<\/h4>\n\n\n\n<p>Commercial products such as Backblaze, iDrive and Carbonite are subscription services that run in the background and continuously back up the documents and data from one computer to the cloud. They generally don\u2019t back up the apps you have installed on your Mac. They are particularly useful for \u201cdisaster recovery,\u201d if your Mac gets stolen or your home gets damaged.<\/p>\n\n\n\n<p>Services such as DropBox, Google Drive, and Microsoft OneDrive, on the other hand, are often used for a different purpose: to share specific folders of files with other users remotely.<\/p>\n\n\n\n<h3 id=\"Local-backup-with-Time-Machine\">Local backup with Time Machine<\/h3>\n\n\n\n<p>Time Machine backs up all the files on your Mac other than macOS itself and the apps that come with macOS. Time Machine backs up all your third-party apps, system files, support files, plug-ins, and sound libraries on your startup disk. If your Time Machine external backup disk is large enough, you can also use it to back up other disks attached to your Mac, such as making backups of project files you record in your DAW. A Time Machine backup on an external disk can also be used with Apple <a href=\"https:\/\/support.apple.com\/en-us\/102551\" target=\"_blank\" rel=\"noreferrer noopener\">Migration Assistant<\/a> to move all your data and apps from an old Mac to a new one.<\/p>\n\n\n\n<h2 id=\"How-to-Create-a-Time-Machine-backup\">How to Create a Time Machine backup<\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2025\/09\/Time-Machine-App-Icon.jpg\" alt=\"macOS Tahoe 26 Time Machine\" class=\"wp-image-1787624\" width=\"240\" height=\"236\" srcset=\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2025\/09\/Time-Machine-App-Icon.jpg 959w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2025\/09\/Time-Machine-App-Icon-300x295.jpg 300w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2025\/09\/Time-Machine-App-Icon-768x754.jpg 768w\" sizes=\"(max-width: 240px) 100vw, 240px\" \/><\/figure><\/div>\n\n\n\n<p class=\"has-text-align-center\"><em>Time Machine in macOS Tahoe 26<\/em><\/p>\n\n\n\n<h3 id=\"What-kind-of-hard-drive-do-I-need?\">What kind of hard drive do I need?<\/h3>\n\n\n\n<p>You need an <a href=\"https:\/\/www.sweetwater.com\/c774--External_Hard_Drives\" target=\"_blank\" rel=\"noreferrer noopener\">external hard drive<\/a> that connects to your Mac over USB or Thunderbolt.
