Verify your backup disk on Mac
If you back up to a network disk, Time Machine periodically verifies that your backups are in good condition. This scheduled verification happens automatically, but you can manually verify a backup at any time.
On your Mac, click the Time Machine icon in the menu bar.
Press and hold the Option key, then choose Verify Backups.
If the Time Machine icon isn’t in the menu bar, choose Apple menu > System Settings. Click Control Center in the sidebar, scroll down to Time Machine , then select “Show in Menu Bar” from the pulldown menu.
Thanks for your feedback.
