When Scheduled Backups are enabled, the app displays a notification after each successful backup with information about how many messages / calls were backed up and failed.
If you are not getting this notification, then the scheduled backups are not working. Here are some potential reasons:
- If you are using a Samsung phone check if you have any power saving restrictions on the app being applied by the phone. To check, open the Battery screen from Phone Settings and see if it shows anything like the screenshot attached. If so, tap on the Details button at the bottom and then look for SMS Backup & Restore in the list and disable power saving for it.
- If you are using a HUAWEI Phone: If scheduled backups are not working on Huawei phones change settings as follows: Settings> Apps> SMS BACKUP & RESTORE> Battery> Keep running after screen off.
- This app can be installed on the SD Card on phones which support it. If the app is installed on the SD Card, then it is not able to start the scheduler when the phone reboots. If you want to use Scheduled backups, please do not install the app on the SD card.
- Whenever an app is updated, Android removes all its scheduled events and the schedules can only be set again by the app when it is opened. Each time you update the app, make sure you open it at least once after the update to enable the schedule.
- Some other “Task Manager” or “Task Killer” app is killing this app, thus making the backup impossible. This is especially a problem if the other app is set to “Auto Cancel” or “Auto Kill” every hour or so. If this is the case, make sure “SMS Backup & Restore” is excluded from the apps which are auto killed.
