What is a Backup File?
The Backup File contains all your entries, moods, activities, and settings. You can export or import it back to Daylio. Use this file to manually backup Daylio data anywhere you like or transfer your data from Android to iOS and back.
Backup File vs manual or automatic cloud backups
The backup File needs to be exported manually via Advanced Options. You cannot use your regular or automatic backup file to transfer data to another platform.
We still strongly advise using automatic cloud backups in addition to using the Backup File. Automatic backups are done after every entry and your data will be always safe.
How to transfer Backup File?
There are many ways to do it and many apps you can use. We will describe the most basic ways to transfer your data.
Before you start, make sure Daylio is updated to the latest version on both phones. You might need to open Google Play or App Store and manually update the app.
Android Export
1Open Daylio > Tap More > Backup & Restore
2If you’re prompted to choose an account press back to close the dialog. (This is an account for Google Drive backups which we are not using now.)
3Scroll to the bottom of the screen and tap Advanced Options.
4Tap the “Export” button.
5Choose Gmail or any other email client. If you don’t see a prompt with an option to choose an email client and some other app is automatically opened instead you might need to “Clear Defaults” for that app. Learn more here…
