Choose the disk you want to use as your Time Machine disk, or setup a Time Capsule device then click Use Backup Disk Choose the backup disk for Time MachineĤ. Hit Select Disk if you haven’t already been prompted (such as when you plug in a new external USB drive)ģ. Open Time Machine (from the Dock, Applications folder or Spotlight) and enable it using the main slider on the left Turn Time Machine on and configure its optionsĢ. Here’s a quick rundown on the basics of Time Machine.ġ. The process is fairly straightforward and will get you back up and running relatively quickly. It won’t let you boot from a backup disk either – in the event of a catastrophic failure you’ll need to boot from a Mac OS install disk if you have one (or Lion’s recovery partition) and then restore using your Time Machine disk. An important point to realise is that Time Machine doesn’t make an absolutely perfect copy of your hard disk – rather, it backups up your documents and files and the most important system files. Once Time Machine is up and running, there’s not really anything you need to do except let it continue its backups quietly running in the background. Once your Time Machine disk is full, it starts deleting the very oldest weekly backups first to make more room. Time Machine also features a very intuitive user interface that lets you zoom back in time to any date you want to restore individual files and folders from. From then on, it makes hourly backups of the changes to your hard disk for the last 24 hours, consolidated daily backups for the last month, and weekly backups for everything older than that. In fact, all you need to do is plug in an external drive and configure Time Machine to use it for backups. Time machine is designed to be very simple to use and nearly invisible. Optical disks can also degrade over time, although they can normally hold data reliably for decades.īy far the simplest way to backup your content is with the Mac’s Time Machine application that has been bundled with every Mac since Leopard was released in 2007. In other words, every so often, make a fresh copy of your data and burn to new disks, and store the older ones somewhere safe. Most people opt for external hard disk drives (USB or FireWire ones) as they’re relatively inexpensive and can store vast quantities of data.Īn important point to realise is that if you use optical disks such as CDs and DVDs, you should regularly retire them. Optical disks are cheap and readily available but you might need quite a lot of them especially if you have a large hard disk on your Mac. So if you’ve got backup disks lying around at home, make sure you store them somewhere physically separate from your computer.Īnother thing to think about is what kind of backup media to use. Imagine the worst case scenario if someone stole your MacBook Pro and the backup disk attached to it – the whole point of backing up is to be able to recover your data in such an unlikely scenario. You might think it would suffice, but most dedicated backup aficionados make two or even three sets of backups and always store one of these offsite. Once you have migrated your user accounts and applications using Setup Assistant or Migration Assistant, you can continue to use CCC to back up your Mac to the same backup volume that you were using for the old Mac.It’s important to realise that one backup is never enough. You can migrate directly from a CCC backup of your old Mac. We recommend that you use the Setup Assistant application (runs on your Mac's very first boot) or the Migration Assistant application to migrate content from your old Mac to a new Macintosh. Your new Macintosh cannot boot from the older version and build of macOS that is installed on your older Mac, so simply restoring your old Mac's backup onto your new Mac won't work. When you get a new computer from Apple, it has a specific version of macOS installed on it, and further, a hardware-specific "build". You may restore data from one Mac to another - use Migration Assistant to migrate data from your CCC backup to another Mac. While this has worked in the past, Apple has made it clear that this is no longer supported. You should not restore a backup of macOS System files from one Mac to another. It is not possible to completely migrate your old Mac solely using Carbon Copy Cloner.
