iTunes Backup did i lose my backup?

okay so basically I deleted whatsapp and the whatsapp backup available on iCloud but before doing that I backed everything up on my itunes pc when i reinstalled whatsapp they said that there was no backup available to restore so I connected my iPhone to itunes to restore and it said there wasnt enough space, I started deleting apps and pics while downloading the newest update. I thought that during the update it will restore everything automatically but it showed backing up message again and here I freaked out because it will over write my old backup that had the whatsapp messages on it. Now i tried mulitple times to do a restore and it says that the backup is corrupted! Does that mean my whatsapp backup is lost? I tried third party apps for extracation and they didnt work please help im stuck

Solution 1:

If you deleted the WhatsApp backup in iCloud and the backup you had in iTunes is corrupted, then your WhatsApp history is gone.

PS: Unless you have made a Windows backup between the moment you made the last good backup in iTunes and the moment it got corrupted, but based on your description this seems unlikely.
