The new --null option allows one to test and play with just the memory checkpointing and network buffering aspect of remus, without the need for a second host. The disk is not replicated. All replication data is sent to /dev/null. This option is pretty handy when a user wants to see the page churn for his workload or observe the latency hit though the latter will not be accurate.

Remus provides fault tolerance for virtual machines by sending continuous checkpoints to a backup, which will activate if the target VM fails. See the website at http://nss.cs.ubc.ca/remus/ for details.
