What is an object copy session?

An object copy session is a process that creates an additional copy of the backed up data on a different media set. During an object copy session, the selected backed up objects are copied from the source to the target media.

Automated and interactive object copy sessions

Automated object copy session

An automated object copy session can either be scheduled or started immediately after a backup. A scheduled object copy session is started at the time you have specified using the Data Protector Scheduler. A post-backup object copy session is started after the specified session finishes. You can view the progress of the automated object copy session in the Data Protector monitor.

Interactive object copy session

An interactive object copy session is started from the Data Protector user interface directly. The Data Protector monitor starts immediately and you can view the progress of the session. Multiple users can monitor the same object copy session. You may want to stop monitoring by disconnecting the user interface from the session. The session will then continue in the background.

Object copy session data flow and processes

What happens in an object copy session?

The information flow of an object copy session is shown in Figure 67 on page 232. When an object copy session is started, the following happens:

1.The Copy and Consolidation Session Manager (CSM) process is started on the Cell Manager system. This process reads the object copy specification for information on what to copy and which options, media, and devices to use. It also controls the object copy session.

2.The CSM opens the IDB, reads the information about the media needed for copying, and writes the information about the object copy session, such as generated messages, to the IDB.

3.The CSM locks the devices. The session is queued until all read Media Agents and the minimum required write Media Agents are locked, with the same timeout as for backup. If the resources are still unavailable after the timeout, the session is aborted.
