Perhaps this is not new information, but it is not known to many. Google automatically deletes backups on Android devices if they have not been used for more than two months. Google allows you to store backups of the Android system in Google Drive, but this happens as long as you use the device.

If the device is not touched for two weeks, Google Drive will begin to display the expiration date of the backup copy. Here, the countdown will be shown before the data is automatically erased. Probably, if at this time to start using the device, this countdown will be removed.

If backups are deleted, you can not restore them, all data and device settings will be lost.

If you contact Google's servers at least once every two months, it will not happen. Many companies also get rid of unused accounts and data, but usually they are clearly warned about this. Users complain that Google does not provide such warnings and removes backups even in paid Google Drive accounts.

Thus, users are advised to take care of the safety of backups on their own, especially if they have more than one Android-device and some of them are lying idle for a long time.
