You can back up iPad using iCloud or your computer. To back up the tablet up to iCloud:
- Go to Settings > [your name] > iCloud > iCloud Backup.
- Turn on iCloud Backup.
iCloud automatically backs up your iPad daily when iPad is connected to power, locked, and connected to Wi-Fi.
Note: On Wi-Fi + Cellular models that support 5G, your carrier may give you the option to back up iPad using your cellular network. Go to Settings > [your name] > iCloud > iCloud Backup, then turn on or off Backup Over Cellular. - To perform a manual backup, tap Back Up Now.
To view your iCloud backups, go to Settings > [your name] > iCloud > Manage Account Storage > Backups. To delete a backup of the device you’re using, choose a backup from the list, then tap Turn Off and Delete from iCloud. To delete a backup of a different device using the same Apple ID, tap Delete.
Note: If you turn on an app or feature to use iCloud syncing (in Settings > [your name] > iCloud > Show All), its information is stored in iCloud. Because the information is automatically kept up to date on all your devices, it’s not included in your iCloud backup.
