Then, rename the Backup folder, for example, to OldBackup or delete it.
Method 2 – Turn off WiFi and Cellular services on your iPhone
Another workaround would be to turn off WiFi and Cellular services on you iPhone before making a backup of it, which worked like a charm for many users.
Alternatively, turning your iPhone on Airplane Mode could also do the trick.

Resetting the network settings on your iPhone may also help get rid of the error message. You can go to the Settings app and tap Reset at the bottom to reset the network settings. Then, sync again and it should work.

- If your computer is on Windows OS, to enter Safe Mode from Settings, you can follow the steps below:

2) Type msconfig and click OK.
3) At the top of the System Configuration window, click on the Boot tab, check the box next to Safe boot, select Network and click OK.

Method 5 – Delete iTunes backups
Some users reported that deleting iTunes backups fixed the iPhone could not be backed up because it has been disconnected problem for them. You may give it a go: go into iTunes > Preferences > Devices, and delete all previous backups.
Method 6 – Check if you have any large-size apps or files on your phone
It could also be possible that some large-size app or file causes the backup interrupted on your iPhone. To resolve the problem, here’re some alternative solutions for you:
- Don’t use such app. Remove it.
- Use such app and store the data into clouds and reduce local storage.
- Some apps contain function not to perform backup through iTune. Enable such feature.
Method 7 – Uninstall any side-loaded apps
If you have side-loaded apps installed on your iPhone, they might be the culprit. Because when some users uninstalled any side-loaded apps on their phone, they immediately were able to make a backup.
That’s it. Hope this helps in resolving the issue.
