This means that in the presence of a NAS 2-bay, ie with two bays for hard drives and enabling the RAID level 1, the data stored in the first disk will be copied automatically in the second.

All this guarantees maximum safety because in case one of the two disks is damaged the other does not lose the stored data. The only thing to do will be to replace the hard disk failure, confirm the RAID 1 and restore the well functioning of your NAS server.
