If you are using Day One Sync (Plus and Premium), it is a great sync option between devices but is also a great backup method. If you ever need to replace or restore your device, simply download Day One again, sign in to your account, and your entries will download to the device again.

Local backups in Day One iOS (2.x) should be restored carefully and with caution. Restoring a backup will replace all your current data in Day One.   If you choose to restore your data, please follow these steps:

iOS Backups

Backups are created every day and a maximum of 20 rolling backups are kept.

  1. Sign out of Day One Sync on all devices.
  2. Create a backup of your current journal data by going to Day One > Settings > Backup and Restore, then tap Create Backup. (This enables you to restore back to your current data, if needed.)
  3. In a web browser, go to dayone.me, log in, click Account, then click Disable Day One Sync. This will delete your current data on the server (not your backup). (Doing this will ensure that you don't overwrite your restored data when sync is re-enabled.)
  4. Tap the backup you wish to restore.
  5. Tap Restore Backup, then tap Verify.
  6. Follow the remaining on-screen instructions.

After restoring your data, sync will be disabled. To re-enable sync, go to Day One > Settings and sign in to your account.

As this is a permanent change, please be cautious when restoring a backup. If you have any questions about this process, don't hesitate to first contact Day One Support.

Mac Backups

Mac data is backed up automatically every day the app is opened with a maximum of 20 rolling days of backups.

To restore past data, follow these steps:

  1. Sign out of Day One Sync on all devices.
  2. In a web browser, go to dayone.me, log in, click Account, then click Disable Day One Sync. This will delete your current data on the server (not the data on your devices) and will disable Day One Sync for your account. (Doing this will ensure that you don't overwrite your restored data when sync is re-enabled.)
  3. In Day One Mac, go to Preferences > Support and click Show Backups. This will open a Finder window where your Day One data is stored on your computer.
  4. Open the Documents folder and delete everything except for DayOnePhotos.
  5. Open the Backup folder. You'll find daily backup folders named with the date of their creation. Open the daily backup folder you wish to restore.
  6. In each backup folder, there are two files: DayOne.sqlite and metadata.plist. DayOne.sqlite is the backup database for Day One. (You can ignore metadata.plist—it will be used in the future when an easier option for restoring files is added to Day One's Preferences).
  7. Option-drag (thus copying, not moving) the contents of your chosen backup folder to Documents.
  8. Open Day One Mac to see your restored data.

Note: The backups for text are stored in this folder: /Users/[USERNAME]/Library/Group Containers/5U8NS4GX82.dayoneapp2/Data/Backup Photos are permanently stored here and are not deleted when entries are deleted. They are stored in this folder: /Users/[USERNAME]/Library/Group Containers/5U8NS4GX82.dayoneapp2/Data/Documents/DayOnePhotos
