Noob question - Adding a mirror?

[pkt666]

Hey ppl :)

I've been expierementing with freenas, and keeping it small for now.

I've made a lil freenas (zfs) box, with a single WD 1TB hard drive in, which I have dumped all my files on.

What I would like to do now (if possible) is plug in a matching WD 1TB hard drive, and mirror all the data from the first HD to the new HD.

Possible? Or should I backup my data and start from stratch?

Cheers ppl :)

ps. it's a 64-bit dual-core amd 3.2 cpu - 8gig ram - running the os off a 1 gig usb - with a 60gig ssd for caching

Is possible.
