You are trying to overwrite a new backup to existing backup file for which expiration date is set.. and this is not advisable. You can try using init skip parameters in your backup command which will initialise the backup file. Firstly existing backup data will be removed and so your data expiration date check would be skipped. Google for init skip params. Best Of Luck.
