Well....IMHO it's not the same thing. The backup on other server is usable if you have another bulding, because if the backup server is in same room if you have fire in you server room you lost everything. With tape you can put the tape more easyly in another room/building. But if you can I recommand you to using rsnapshot (it's in ports) it's set of perl script base on rsync and it's very wonderful tool.
