Archiving solutions have different stages to process the email data. Below the four stages of the archive process are described.
Copying - In this stage all messages that are eligible for archiving are copied from the primary store to the archive store. When a copy of a message is made, an internal reference to this copy is placed in the original message.
Stubbing - In this stage all messages that are eligible for stubbing are stubbed. A stub is defined as the original message with the body and attachments removed. A message is eligible for stubbing when it reaches the specified minimum age AND archived copies are present. So a message is never stubbed if it’s not yet copied to the archive store.
Deleting - In this stage all messages and stubs that are eligible for deletion are removed from the primary store. A message is eligible for deletion when it reaches the specified minimum age AND archived copies are present. So a message is never deleted from the primary store if it’s not yet copied to the archive store.
Purging - In this stage messages that reached a specific age will be deleted completely from the archive store. In this case messages will not be available on both the primary and archive server.
Every of these stages can be configured in the configuration file of the Archive Controller. Before deploying the Zarafa Archiver make sure the configuration options are carefully set according to the archive strategy. The default installed configuration will only copy message items from linkes mailboxes to the archive mailboxes.
