No real writeup. With Ubuntu you will need to add the mdadm and samba packages. mdadm is for making and administering the RAIDs. samba is so windows can see the RAIDs as a remote volume. If you are doing Linux to Linux backup, then use the auto mounter and NFS for mounting the disks. I have mdadm and the kernel do all the RAID work rather than use a RAID controller as modern CPUs do the work faster. Also many RAID controllers are not supported in RAID mode under Linux. I'm such an old UNIX fart that I don't bother with the auto mounter and just use hard mounts and directly tweak the exports file. I also just edit the samba files directly or in the case of my last box I just copied them over and edited a couple of names in them. Ubuntu has a gui interface to configure samba. I have no clue how to use it or what it is called.
