I have an older server with two hard drives in a raid and a tape backup. The data on the drive that needs to be backed up is more than the tape will hold. I am debating between getting an external hard drive and a network attached storage device to back up the data. For security I like the idea of the NAS being in a different part of our building but I don't know if this make is a better choice than an external drive. No one needs to be able to access the data on the backup device except in the event of server failure. I have tried to compare them on my own but I have been overwhelmed with the online information.
In your experience, what is the easiest and most efficient hardware device to use in a nightly server backup?
