Of course we don't know what your data consists of, but I agree with TeknoJnky that you should not adopt this as your backup strategy:
1. Your backup is difficult to read, other than in a readynas system.
2. The sata connectors are not built for repeated disconnection/ connection cycles, this may in theory shorten the life of the disks, as may the repeated volume rebuilds that are going to be required.
3. Your backup is potentially 1 month old when you need it - this may be ok for you of course.
