Time Machine must erase your existing backup history and start a new backup to correct this.

I've read the responses to this problem. And yes, starting a new backup does help but does not recover history. I checked the drives (NAS on LAN) they are fine and perfect. Backup recover is fine as well. Is there a "real" solution to this problem?

Thanks!

No. Sometimes, running Disk Utility / First Aid on the backup disk will provide some temporary relief, but it is not a long term fix.
