@DustinB Yeah I thought about doing something like this, but then we are getting into overkill costs lol.
My main point behind this post was to get info on what other people are doing, I presumed most are just relying on config backups and will restore it at the other site if needed, which is fine.
I was just also debating about whether or not I wanted the subnets to match between these 2 sites, since that can create some routing headaches, but should still be doable and would make recovery even faster.
@olivierlambert yeah I do use that feature, so that's very helpful! Should make this all doable.
