What is backup?
A data backup is a process of copying or archiving information located in files and folders for the purpose of being able to restore them in case of data loss.
Why does Android need to backup?
The sole purpose of backup data is to save or not to lose your important information such as emails, contacts, apps saved, Wi-fi passphrases or most of the passwords in case of accident, loss or sudden virus, theft or breaking of your device.
Where does the Android backup data?
Built-in to Android is a backup service, this service automatically backs up things like your device settings, Wi-Fi networks, and app data to Google Drive. The service is free and doesn’t count against storage in your Google Drive account.
Google’s backup service is built into every Android phone but this service should be turned on by default after you set up your Android device, but you should double-check that’s indeed the case.
What are the types of Android backups?
Backup most of your data is very easy with Google, and it has gotten far easier. Android provides three ways to backup their data to Google drive:
Auto Backup data, is for Android 6.0 version and above devices (API level 23), preserves data by uploading it to the user’s Google Drive account. This includes files in most of the directories that are assigned to your app by the system. Auto Backup data can store up to 25 MB of file-based data per app. Auto Backup data is recommended because it’s enabled by default and requires no work to implement. The Auto Backup feature is a file-based approach to backing up app data.
The Key/Value Backup feature (formerly known as the Backup API and the Android Backup Service) preserves settings data in the form of key/value pairs by uploading it to the Android Backup Service. It is typically not appropriate for app data contents, such as media, downloaded files, and caches, unless the amount of data is very small. Backup data is stored in Android Backup Service and limited to 5MB per app. Google treats this data as personal information. In Key/ Value backup Apps must implement a Backup Agent that defines what data to backup and how to restore it.
This full backup is also a convenient option for those who have something very important and don’t want to lose any bit of data.
What data included in the Auto backup?
Google, automatically backup’s the data from Android to its built-in backup service. By default this Google backup service restores most types of that are you care about and associate with, where you can also access it on Google drive.
