    Synchronous distributed and backup

    Luc DEW Newbie

      Hi,

       

      I am evaluation infinispan 6.0 and I have questions regarding the synchronous distributed cluster mode.

       

      I did some tests with 4 nodes synchronizing with JGroups in tcp. I put 800 Mbytes of data in the cluster (each VM started with > 1Gbytes), then stopped adding any data.

      If a node was lost, I could still access any entry of the cache from any of the remaining nodes.

       

      However as soon as I lost another node with 2 remaining, some entries were lost.

       

      What is the backup strategy in the distributed mode ? Is there any backup at all (if you say no I think i have to review how my test was implemented ;-) )

      Can the number of backup nodes when an entry is added be configured ? ( I am not referring to near cache).

       

      Regards,

      Luc
