XDCR / WAN replication for DR site in couchbase 1.8
I can see that couchbase 2.0 has new support for XDCR: http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-admin-tasks.... I'm setting up a second couchbase cluster in a DR data center on the west coast (primary / live cluster is on the east coast).
What is the best approach to take to replicate all of my live cluster data to my off-site west coast DR cluster? I found this forum entry but it doesn't provide much info: http://www.couchbase.com/forums/thread/membase-over-wan-dr-site.
I'm leaning towards using a custom PHP script with HTTP calls across the clusters in order to manually replicate the data. I'd also be curious about anyone who has used rsync on the couchbase data folder as that could possibly work to replicate the data between the clusters. Lastly it'd be great if couchbase had something built in with 1.8 that works with WAN replication.
Any info would be great, thanks!
