You can configure redis to persist all data to disk and configure your machines in master slave replication.

Redis sentinel (built in redis 2.7+) can be also used to do automatic failure recovery (promote one slave as master when master is down)

You can find all the documentation you need about this on the redis docs website http://redis.io/documentation

  • Thanks for the answer. but both of my servers will be handling data so how much time it will take to sync ??? does write to redis master server auto sync to redis slaves ??? How much time it take to sync a data written in master ??? is this time is configurable ?? – Vishnu Apr 18 '13 at 12:54
  • slaves are kept in sync master as much as possible (depending on traffic / IO capabilities there might be some replication lag), when a slave connects to a master it syncs and then replays all the commands that are sent to the master. – Tommaso Barbugli Apr 18 '13 at 13:21
