Replication of the default tenant

For the default tenant, the Replication service works on one or more selected directories directly under fcfs_data in the default namespace. The service replicates the entire directory hierarchy under each selected directory.

Default namespace properties

Directories in the default namespace on one system involved in a replication link can be replicated only to the default namespace on the other system involved in the link. They cannot be replicated to HCP namespaces.

Additionally:

Before you can include any default-namespace directories in a replication link, the default namespace must exist on both systems involved in the link.

The default namespaces in the two systems must have the same cryptographic hash algorithm and retention mode.

The default namespace can be configured to prevent writes and deletes. This configuration can differ between the default namespace on the two systems involved in a link. However, even if the system receiving data is configured to prevent these actions, changes to namespace content on the sending system are replicated.

Replicated directories

You select directories for replication when you create the replication link. You can select additional directories or deselect directories by modifying the link at a later time. A replication link can include at most 256 directories.

Directories can be created in the default namespace on both of the systems involved in a replication link, so the two systems can have directories with the same name. You cannot replicate a directory created on one of the systems if a locally created directory with the same name already exists on the other system.

The one exception to this is the directory used for email archiving through SMTP. You can replicate the email directory if the email directory name is the same on both systems.

Replicated changes

With an active/active link, replicated directories are read-write on both systems involved in the link. All changes made to the content of those directories on either system are replicated to the other system.

With an active/passive link, the replicated directories are read-write on the primary system and read-only on the replica. Users and applications cannot make any changes to the content of the replicated directories on the replica. However, all changes made on the primary system are replicated to the replica.

Replicated items

The Replication service replicates these items for the default tenant:

Existing objects, object creations, object deletions, and metadata changes in the directories being replicated

Retention class creations, modifications, and deletions for the default namespace

Content class and content property creations, modifications, and deletions

All log messages relating to retention classes and privileged delete operations
