- Tip: How to Back Up your Samsung Device Data when Samsung Cloud Sync Failed

Method 1: Charge your Samsung When Samsung Backup Failed
Be it auto backup or manual backup, Samsung Cloud will consume power to save your data to the cloud. And due to Samsung’s policy, if your Samsung has lower than 15% power, any attempt of sync and backup will fail.
So, check your Samsung battery remaining, charge it when it’s lower than 15%. And you can just leave the home be, as Samsung Cloud will then sync the phone data to the cloud automatically when the power is sufficient.

Method 2: Check the Cloud usage When Samsung Backup Failed
Samsung Cloud is free for the first 15 GB capacity. When you use all the 15GB, what will happen? Samsung Cloud will just stop syncing any byte of data to the drive.
Now, launch Settings, go to Cloud and accounts - Samsung Cloud. There, you can see a circle chart there to show you the how many storage are used.

If it's full, try to delete some data from the cloud by unchecking some options below. This removes some data from the backup.
Or go to Settings - Apps - App Settings (three dots) - Show System Apps - Samsung Cloud - Storage - Clear Data - Clear Cache. This will erase all the caches from the app and release some space.
If you have too much data for backup, deleting caches is not helping, try to pay for a bigger capacity then.

Method 3: Reboot your Samsung Device When Samsung Backup Failed
Whenever we encounter issues on our Samsung, there’s always one general solution we can try - reboot your Samsung.
By rebooting the Samsung, some of the wrong settings and bugs will be removed. To reboot your phone, simply press down your Samsung phone’s power button until there is a window pop-up appearance. A restart option will appear and simply select it to restart the phone device.
Method 4:Reconfigure the Network Connection When Samsung Backup Failed
By default, Samsung Cloud will sync your Samsung data via Wi-Fi. So, if you’re using mobile data, Samsung Cloud backup will just fail. You can change the backup settings through Settings - Cloud and Settings - Manage cloud storage - Settings (three dots) - Sync using Wi-Fi only.
On the new screen, choose to allow using mobile data to back up data to Samsung Cloud.

Tip: Weak Network Connection Ruins Backup
Performing Samsung Cloud data backup requires that the network connection is strong or reliable. A network connection that is unusable or weak can lead to the failure of Samsung Cloud backup.
To fix this particular problem, change the type of network connection. You can change from cellular data network to a Wi-Fi network connection or vice versa.
Method 5: Log Back in your Samsung Account When Samsung Backup Failed
Another valid solution is to log out your Samsung account on the phone first, and log back in. So far, there’s no explanation for this method, telling us why it would work. But it’s definitely worth a try since many who had this issue fixed it by logging back in their account.
So, let’s follow their experience and open the Settings app on your Samsung. Proceed to the Cloud and Account option, and choose Samsung Cloud.
Open a menu by simply tapping on the 3 dot icon and in the list displayed select Settings. Choose the Remove account option to exit your account and at that point, add the account back to your Samsung phone.

Method 6: Update Samsung Software and Samsung Cloud When Samsung Backup Failed
Samsung Inc. never stops upgrading their software. And if you’re still using the old Samsung cloud or software, update it or them. Errors happen when the system and the program are incompatible. Also, an update will fix most of the simple bugs from your Samsung phone.
