If your phone was updated to
Android 8 from
Android 7, follow the same backup procedure as before. See
Backing up an Android 6 or 7 phone.
Note: To back up SMS messages on a phone, such as HTC 10, that was updated from
Android 6 to 7 and then to
Android 8, you need to remove your
Google Account—the one that you use as your backup account—and sign in to this account again.
Follow the steps below to back up an HTC phone that's preinstalled with
Android 8.
Auto Backup periodically backs up your phone to a private folder in
Google Drive. It occurs every 24 hours when the phone is idle, charging , and connected to a
Wi-Fi network.
Backup data will not count towards your
Google Drive storage quota. Large files or files that app developers have chosen to exclude from the service will not be backed up.
