If you need to create a new backup from Mac
If you must create a new backup, that means a problem has occurred that prevents Time Machine from using the existing backup.
Try to retrieve data from the existing backup
On your Mac, click Back Up Later.
Click
in the menu bar, then choose “Browse Time Machine backups”.If the Time Machine icon isn’t in the menu bar, choose Apple menu
in the sidebar, scroll down to Time Machine , then select “Show in Menu Bar” from the pop-up menu.Use the arrows and timeline to browse the backups that contain the files you want to retrieve.
Time Machine asks you again later to start a new backup.
Create a new backup
Click Start New Backup. Your existing backup is deleted, and your data is fully backed up only after the new backup is completed.
To minimise the risk of needing to create a new backup, consider doing the following:
Ensure that your external backup disk’s firmware is up to date. If you back up to a Time Capsule, check the Apple Support website to be sure you have the most current firmware available.
If given the choice between AFP and SMB, use SMB to back up to your external backup disk.
Use an uninterruptible power supply (UPS) with your external backup disk to prevent unexpected power failures.
