I also think that's a good question and currently without a "use this" answer :-) I think it shouldn't be hard to write a Solr service querying ZK and replicate both conf and indexes (via SnapPuller or ZK itself) so that such a node is responsible to back up the whole cluster in a secure storage (N

What sorts of failures are you thinking of? Power loss? Index corruption? Server overload? Could you keep somewhat remote replicas of each shard, but not behind your load balancer? Then, should all your customer facing nodes go down, those replicas would be elected leaders. When you bring the cus

I'm thinking about catastrophic failure and recovery. If, for some reason, the cluster should go down or become unusable and I simply want to bring it back up as quickly as possible, what's the best way to accomplish that? Maybe I'm thinking about this incorrectly? Is this not a concern? --

He explained why in the message. Because it is faster to bring up a new host from a snapshot. I presume that he doesn't need the full cluster running all the time. wunder On Sep 20, 2012, at 2:19 PM, Markus Jelsma wrote: > Hi, > > Why do you want to back up? With enough machines and a decent

Hi, Why do you want to back up? With enough machines and a decent replication factor (3 or higher) there is usually little need to back it up. If you have the space it's better to launch a second cluster in another DC. You can also choose to increase the number of maxCommitsToKeep but it'll tak
