The Alfresco server can be clustered together to have a more robust, scalable, and highly available ECM server. Alfresco provides you with the flexibility to distribute the nodes and cluster them in multiple tiers based on your requirements. Repository and Share clustering is supported by Hazelcast. The Admin Console of Alfresco provides you with details about all the clustered nodes and also allows admin users to verify the clustering of nodes. Alfresco doesn't provide its own backup and restore process, but we can use industry-standard filesystem and database backup mechanisms to ensure a robust backup of your applications.

In the next chapter, we will talk about how Alfresco actually stores content. The content lifecycle will also be discussed in detail. This chapter will also cover in detail the important tables in the Alfresco database.
