How to backup and restore like a boss

Android

The backup process is very simple:

Go to More > Backup & Restore
We advise you to use automatic backups - so your data is always safe.
For a manual backup tap the button violet Backup to Google Drive
- If you are doing this first time you need to select your Google Account you want to use. (You can always log out and use another account.)
If the backup is successful, you see the confirmation message "Yay! Backup created." and the date of your backup will change.
Now it is safely stored on your associated Google account although you cannot see it there - but the app can. Where are my data when I backup to Google Drive?

Go to More > Backup & Restore and tap the menu item "Restore..."
You will see the list of your recent backups. Select the one you want to restore.
It will display a message "Restoring backup… it can take a few moments. Have a cake!"
When the backup is restored you will see the message "Woohoo! Backup restored." and you will see your entries in the app.

If something went wrong to make sure you are online.
Also, there might be an issue with Google Drive. You have to wait and try in few minutes or hour.
Are you trying to import CSV file? This is not possible. You have to use native Daylio backup functionality.
Do you use the same account for restore and backup? Verify your account at the bottom of the screen.
When everything failed there might be some 3rd party issue. It always helps to kill the app or restart the phone.
