NAS326 Corrupted file recognised by backup?

lacc47

I have nas326 with two disks. I configured two independent BASIC volumes from the disks, so there is no RAID. One disk (volume1) is for daily use, and is shared to internal network. Another disk (volume2) is for making regulary (monthly) backups from volume1. Volume2 has no shared folder on network, only NAS can access it (while making backup). 

My question is: If there will be in the future a file witch is damaged by disk error on volume1, shell I be notified by the backup?

Second question: Is there any tool for making disk integrity check, or this is made from nas regularly automatically?

thanks
