@@ -40,43 +32,51 @@ Apart from the performance requirements, we also need a storage system
 to ensure multiple-level data safety and support fast data migration
 between data centers, automatic load balancing, and online partition split.
 
-After investigating the existing storage systems in the open source world,
-we could hardly find a suitable solution to satisfy all the requirements.
-So the journey of Pegasus begins.
+## Features
+
+- **Persistence of data**: Each write is replicated three-way to different ReplicaServers before responding to the client. Using PacificA protocol, Pegasus has the ability for strong consistent replication and membership changes.
+
+- **Automatic load balancing over ReplicaServers**: Load balancing is a builtin function of MetaServer, which manages the distribution of replicas. When the cluster is in an inbalance state, the administrator can invoke a rebalance command that automatically schedules the replica migration.
+
+- **Cold Backup**. Pegasus supports an extensible backup and restore mechanism to ensure data safety. The location of snapshot could be a distributed filesystem like HDFS or local filesystem. The snapshot storing in the filesystem can be further used for analysis based on [pegasus-spark](https://github.com/pegasus-kv/pegasus-spark).
