Abstract
Example implementations involve a plurality of servers, network, and storage systems, wherein some of the servers may execute data programs and store primary data in the memory of the servers. Some of the servers may also execute a standby data program. Storage devices may provide for a snapshot volume, a log volume, and a recovery volume, and executes a recovery program to store a recovery image into the recovery volume from the data of the snapshot volume and the log volume. On failure of the server, the standby data program loads the recovery image of the recovery volume, which can reduce the time to commit logs to the snapshot image.
