There are overall security issues such as the physical security of the tapes, control of
access to the backup devices and servers, and administrative control for access to the backup
software. An additional concern is that the backup may be going over an Ethernet IP network and it
needs to be secure. That can be done using some security on the transmission, such as IPsec, or
having a network that is sheltered from any outside access. Other than that, the backup of a NAS
device has the same security concerns as backing up block storage system data.
