Data backup is a must-to-do task with your phone as there are many situations that cause data loss. Without backup, it is really hard to recover those deleted or formatted data on your phone. Luckily, you can easily backup a lot of content to computer with HTC Sync Manager, including personal settings, private data, media files, documents and email accounts.
HTC Sync Manager will start automatically after connecting HTC phone to computer through USB cable. Click Transfer & Backup ->Backup and Restore. There are two options you should notice about. One is 'Choose whether to include media content from your phone in the backup'. If you checked it, then all media files will be backed up as well as personal settings. Another option is 'Choose whether to always back up your phone whenever you connect it to your computer.' Once it was checked, the phone will be backed up automatically when the phone was being connected to computer.
Please select the options accordingly and click Back up now to start the backup process. At this time, you can also add a password to encrypt the data to protect it from unauthorized access. All the selected data will be backed up to your computer and you can restore it at any time.
