Lost my backup: password is incorrect

Question

I have lost all my memories updating to the next iOS system.
I have never put a password to my old iPh backup, but iTunes,
without being asked, tells me that I have to insert one.
That's devastating. Everything's lost. Someone knows how to fix this problem?
I've tried old passwords, with or without caps letters, 0000, 00000, 1234, 12345, 9999, click cancel, renewing a new AppleID password  but nothing worked. I've tried also the trial version of Elcomsoft password recovery tool (= password don't exists)
I've a Windows 7 machine.
Please help me (photos, numbers, notes), maybe exists a sort of password.
That's really unpleasant since I'm a physician and lots of documents were important and private informations.

Answer 1

iTunes does not and can not set up password protection for your iPhone's backup, which must be entered twice for confirmation.
Contacts are designed to be synced with a supported address book app on your computer and there are a number of free email accounts that support syncing contacts over the air with iOS devices. Never a good idea to depend on an iPhone or any cell phone alone for such important data.
Notes can be synced with a supported application on your computer as well.
Photos/videos in the Camera Roll can and should be imported by your computer as with any other digital camera.
Unless you have a good friend on the CIA or law enforcement with state of the art encrypted password detection equipment, consider your backup and the data within as gone.
