This chapter provides the information needed to manage Native Replication configuration and monitoring of ProtecTIER® VTL systems.
Native Replication lets you replicate data objects between ProtecTIER repositories. In order for a logical set of repositories to replicate from one to another, you must create a replication grid. The replication grid is remotely created and managed by the Replication Manager.
The ProtecTIER Replication Manager is a server that remotely manages the replication grids within an organization. ProtecTIER Manager connects to the ProtecTIER Replication Manager using the IP address of the ProtecTIER Replication Manager server. The ProtecTIER Replication Manager is installed on a ProtecTIER node and can manage up to one grid with 24 repositories.
Each ProtecTIER Replication Manager has a unique identity. A repository, once it has joined a replication manager cannot join a replication grid managed by a different replication manager, even if it has left the grid. This restriction prevents data collision.
In a VTL environment, replication groups are created where multiple source repositories can replicate to a single target. This target can then act as a Disaster Recovery site for any number of the sources, while still allowing local backups, as well as replication, from the active source repositories.
