About CASO catalog locations

In the CASO environment, you can choose the catalog location. Regardless of the catalog location, if a persistent network connection is available between the central administration server and the managed media server, then you can browse the backup sets in the catalog and perform restore operations from both servers.

The following catalog locations are available:

Description

Distributed

Image files, which are small files that contain information about the backup set, are distributed to the central administration server from every managed media server. History files, which contain detailed information about the backup set, remain on the managed media server.

Note:

It is important that you back up the catalog files on the managed media server since most catalog information is kept here when the distributed catalog location is used.

When the catalog is distributed, the view of the restore selections on the central administration server displays only the backup set at the volume level. Backup set details are not displayed if the managed media server that created this backup set is not available, but the whole volume can be restored from the central administration server.

A distributed catalog provides increased performance, default centralized restore capability, and decreased network traffic. If a managed media server does not have a persistent connection to the central administration server, then whenever the managed media server does connect, the image files in the catalog are automatically distributed to the central administration server. The temporary increase in network traffic caused by the catalog distribution is not significant.

Centralized

All catalog files and information for the managed media server are kept on the central administration server.

Replicated

All catalog files are replicated from the managed media server to the central administration server. Both the managed media server and the central administration server store the catalog produced by the managed media server.

Deletions of catalog files are replicated between the managed media server and the central administration server only when the catalog files are deleted by Backup Exec according to the catalog settings. If catalog files on the managed media server are deleted as a result of a backup job or a manual deletion, the deletions are replicated the next time that the catalogs are synchronized.

When choosing the catalog location, consider the following:

  • If there is enough available disk space on the managed media server to keep a distributed or replicated catalog.

  • If there is enough network bandwidth to handle the traffic generated by a centralized or replicated catalog. Centralized and replicated catalogs require a high bandwidth network connection.

  • If it is important for your data recovery needs to keep catalog information in one location. For example, when the catalog location is centralized or replicated, all catalog information is kept in one location, which makes it easier to back up. When the catalog location is distributed, most catalog information is kept on the managed media server.
