I see this topic is quite a popular ([1], [2]) so hopefully I can get nice feedback on what I'm trying to do. I'm buying an HP Microserver with 4x 2TB, and I currently have two computers. I'd like this microserver to become my "databank" in many respects:

1. I want to configure my computers so they can automatically backup to this box using the Ubuntu utility (Deja-Dup).


2. I want to install a Git server, a local dropbox and a media server (from what I know, either Plex, xbmc or this post, or any good suggestion)


3. Ideally, and because of the little I know about it, I'd like my filesystem to be ZFS and I also need help for configuring my zpool in the most efficient way.

About ZFS

I want my filesystem to be fast in reading, very reliable and to support a single disk crash, but I don't require it to be fast in writing. There are four disks, all 2TB - 7200rpm - 64MB cache. I want to make the most of them, in that respect for instance, plain mirroring doesn't seem to be the way to go. But I have no previous experience with ZFS, hence my request for help. I'm thinking of installing Ubuntu Server 12.04 as my operating system, and use ubuntu-zfs.

• How should I configure my zpool to make the most of my four 2TB HDDs?

Many many thanks in advance, J
