Hi Tuco, You're speaking about PARTITIONED cache with custom number of backups [1, 2]. You may specify how many copies partition will have. For example, You have 3 nodes and number of backups set to 1, that means each partition has 1 copy on other node. In other words, if one node failed - you'll not lose data. If number of backups 2 - 2 nodes could be failed without data loose, and so forth.
