This Deployment Guide provides more information about the Zarafa Archiver on different configurations and setups. This information can be used for architects, IT manager and engineers to support their decision making process on archiving strategies.

The Zarafa Archiver provides a Hierarchical Storage Management (HSM) solution for the Zarafa Collaboration Platform, with the following features and advantages:

With the Zarafa Archiver older messages will be automatically moved to slower and thus cheaper storage. The slow storage consists of one or more additional Zarafa Archive servers which sole task it is to store archived messages.

Although the older messages are stored on different servers, the user will not notice this as the Zarafa Archiver provides transparent stubbing. Older messages can still be accessed from the main mailbox of the user, by using the (de)stubbing feature.

To activate the archiving function for users, they need to be coupled to an archive mailbox. The archive mailboxes will be located on one of the archive servers. The archive servers have exactly the same storage architecture as a normal Zarafa server, all mapi properties are stored in a MySQL database and all attachments are stored compressed on disk.

The Zarafa Archiver uses the Zarafa’s multi-server technology to access archive stores in a seamless way using transparent user authentication. Nonetheless, the Zarafa Archiver can be used in a single-server setup with limited functionality.

Zarafa Archiver is an additional product and is not a default component of the Zarafa Collaboration Platform. Subscriptions of Zarafa Archiver can only be used with a valid subscription on the Zarafa Professional or Enterprise edition.
