I have an iPhone 6s and I'm using iOS 11.2.5
I tried running a backup from iTunes, but got the following error:
iTunes could not back up the iPhone "[iphone name]" because an error occurred while reading from or writing to the iphone.
I've tried multiple computers, OSX, Windows, older iTunes, but always got the same error.
On OSX I've opened the Console app, to see what's going on in the background, and found that the following lines are logged, when the error happens [image]:
error [date] BackupAgent2 <private> error [date] BackupAgent2 Error uploading "<private>" to "<private>": <private> error [date] BackupAgent2 Backup error - <private>
I found on some forums that this error log message used to contain a filename instead of <private> (which usually were a corrupted image file) and as a user removed it on the phone, the error disappeared. But it looks like Apple suppressed a lot of things in logs.
I also found a command
sudo log config --mode "private_data:on" to force display these <private> data, but this seems to work on OSX apps only, not on iPhone logs.
So unfortunately here, I came to a dead end.
Can someone help me identify the corrupted file(s), force displaying more detailed errors, or tell me anything else I can do?
