Summary
Alfresco Explorer has administrative utilities to export data from the Alfresco repository, and to import data to the same repository or to another repository.
You must back up data at regular intervals, in order to protect your data from hardware failure. Consider the hot backup deployment option of Alfresco for high availability. If you need a high performance repository, then you should consider deploying Alfresco in a clustered environment.
The upgrade scripts in Alfresco help you to upgrade to newer versions automatically. It is recommended that you try an upgrade on a test or staging server, before upgrading the production server.
Alfresco ECM can be configured as a true single-instance multi-tenant environment. This enables multiple independent tenants to be hosted on a single instance.
