Near-synchronous, meaning RPO X--->0
Many Solaris solutions are using AVS for this. But you could use
block-level replication from a number of vendors.

I realize performance will take a hit.
In general, yes. But it will depend quite a bit on the workload.
For normal file system workloads with writes deferred up to
30 seconds, you may not notice the replication hit. For sync
workloads, it is more likely to be noticeable.
