Microsoft has released a new app which allows Windows Phone users to take a backup of your contacts and messages on Windows Phone 8.1 devices. The app called “Contacts+message backup” is now avialable in the store and can be downloaded on your phone. The app once installed will be able to backup your contacts and SMS to your SD card.
The contacts will be backed up in VCF format while messages in XML format to the SD card so that you can use it to restore to another Windows Phone.
Unlike other apps from Microsoft, this feature is not available as an app once installed. This is available in the settings and you can backup and restore contacts and SMS from there. You can selectively back up, which means you can either choose contacts or SMS. Backup is stored in ‘backup+restore’ folder on the SD card.
There is a known issue in the app that restoring a backup of messages from a dual SIM Windows Phone restores all messages to message store for the first SIM/slot.
The app will work only on phone which support an SD card, so flagship devices will not support this feature.
