Mac Time Machine Manual
Your Time Machine backup disk might not always be available, so Time Machine also stores some of its backups on your Mac. These backups are called local snapshots.
This wikiHow teaches you how to connect and set up the AirPort Time Capsule to a Mac computer. The Time Capsule is a two-in-one device that acts as a Wi-Fi router and an external hard drive which automatically backs up all the computers on your wireless network. On your Mac, click Use As Backup Disk, then follow the instructions in Time Machine preferences. To open Time Machine preferences, choose Apple menu System Preferences, then click Time Machine.

How to use local snapshots
When your backup disk isn't available, Time Machine automatically uses local snapshots to help you restore files. Reconnect your backup disk to make even more backups available.

Page 70 MY BOOK LIVE USER MANUAL Mac Backups (For Mac OS) The Mac Backups section of the page allows you to configure your Apple Time Machine settings for your Mac backups. Using Mac Backups, you can indicate the maximum amount of space you’d like to use on your Time Machine to backup your files. Page 71: Network Settings.
How local snapshots use storage space
You don't need to think about how much storage space local snapshots are using, because they don't use space needed for tasks like downloading files, copying files, or installing new software.
Your Mac counts the space used by snapshots as available storage. Even so, Time Machine stores snapshots only on disks that have plenty of free space, and it automatically deletes snapshots as they age or as space is needed for other things.
If you want to delete local snapshots manually, turn off Time Machine temporarily:
- Open Time Machine preferences from the Time Machine menu in the menu bar. Or choose Apple menu > System Preferences, then click Time Machine.
- Deselect ”Back Up Automatically” or click the Off/On switch, depending on what you see in Time Machine preferences.
- Wait a few minutes to allow the local snapshots to be deleted. Then turn on Time Machine again. It remembers your backup disks.
How often local snapshots are saved
Mac Manual Time Machine Backup
Time Machine saves one snapshot of your startup disk approximately every hour, and keeps it for 24 hours. It keeps an additional snapshot of your last successful Time Machine backup until space is needed. And in macOS High Sierra or later, another snapshot is saved before installing any macOS update.
