Daily backup can only be enabled when the Dropbox sync is enabled, as it needs to access some server storage to store the backup.
On the Dropbox server, it keeps around 30 days of backup for each device, and it is in the folder Dropbox/Apps/ATracker/Documents or Dropbox/Apps/ATrackerPRO/Documents.
The file has the date in the file name. E.g., “Backup_iPhone 6 plus_24.ATracker” means it is a backup from the device “iPhone 6 plus” taken on the 24th.
To restore the backup, send the file to yourself or drop it via airdrop and open it in ATracker / ATracker PRO and follow the guide. Using the Apple Official email app or airDrop function in Dropbox is recommended. Unfortunately, some third-party app does not support data import into ATracker.
To keep data consistent, you must disable Dropbox Sync on all your devices using ATracker and choose the option to delete server data when you disable it. Or manually remove Dropbox/Apps/ATracker/MainStore.v2 or Dropbox/Apps/ATrackerPRO/MainStore.v2 folder.
