mirroring two local pools

[nanodec]

Hey guys,

The answer to this may be simple, and could be obvious, but looking through the FreeNAS guide didn't give me a good explanation.

Basically I have two local pools to mirror. One visible and one that won't be. Want to have this so if the visible pool gets filled, I can remove, extend and resilver it off the hidden one. This is for data redundancy, and I know there could be other ways to go about it, but I've read somewhere that this can be done as a successful option.

How would I go about doing this? Via rsync? I am just unsure of how to specify the local PC versus a remote.

Any insight into this would be awesome... thanks again,

Craig

You can't "mirror" two pools. You can, however, back one up to the other (note that a single catastrophic incident, like a PSU that decides to start outputting 230V AC on its outputs, will probably render both pools unusable). Rsync is a frankly silly choice, but ZFS replication should work nicely.

Awesome Eric...

So how would I go about setting up the zfs replication for local?

Same as regular remote but use 127.0.0.1 and turn off encryption and compression. Note: it uses snapshots so you have to configure that first, but it's also in the docs.

Cool... I have snapshots up and running, I was just wondering how you setup the duplication. :)
