When you sign in with your Microsoft account on your Windows Phone 8.1, you can turn on a service that lets you automatically save important things to the cloud so you'll have a backup if something happens to your phone.
You can choose how your phone backs up your apps, settings, text messages, and photos and videos. In the App list, just go to Settings
This topic is about Windows Phone 8.1. If your phone is running Windows Phone 8, some options and icons may look a little different, and some features may not be available. Check to see which software version you have and find out if an update is available.

One of the toughest things about replacing a lost phone or upgrading is getting your accounts, apps, and settings just the way you like them on your new phone. To make the transition easier, we can back up:
To automatically create a fresh backup, your phone needs a Wi-Fi connection and must be plugged into a power source.
After three weeks without a backup, your phone will prompt you to create a new one.
You can do a manual backup at any time. In Settings
Automatically back up your SMS and MMS messages to the cloud. That way, if you get a new Windows Phone or reset your current one, you can restore your conversations when you set up the phone.
When you delete your messages from your phone, they'll be deleted from the cloud as well, so you're always in sync.
Turning off backup won't delete previously saved SMS and MMS messages. To delete messages from the cloud, turn on backup and delete the messages off your phone.
On Windows Phone 8, you can also turn Chat backup on
Automatically upload your photos and videos to OneDrive and get to them later from any computer or device that connects to the web. (This might use your data plan and incur charges.)
You'll need a Wi-Fi connection to automatically upload videos and best-quality photos.
Deleting backups on your phone only removes the local copy, but you can delete backups permanently from OneDrive. Log in to your OneDrive account and go to Settings > Options > Device backups. You'll see a list of your backups and can delete any you want.
You may want to connect to a Wi-Fi network during setup. The restore can use a lot of your cellular data and you may incur charges.
If you've updated to Windows 10 Mobile, we don't recommend restoring your Windows 10 Mobile backup on a Windows Phone 8. If you still want to restore a Windows 10 backup, rename the phone first to avoid overwriting your backup by going to Settings
