Object consolidation sessions
This section describes how an object consolidation session is started, what happens
during the session, and the processes and services involved.
What is an object consolidation session?
An object consolidation session is a process that merges a restore chain of a backup
object, consisting of a full backup and at least one incremental backup, into a new,
consolidated version of this object. During an object consolidation session, Data
Protector reads the backed up data from the source media, merges the data, and
writes the consolidated version to the target media.
For more information, see Chapter 11 on page 257.
Automated and interactive object consolidation sessions
Automated object consolidation session
An automated object consolidation session can either be scheduled or started
immediately after a backup. A scheduled object consolidation session is started at
the time you have specified using the Data Protector Scheduler. A post-backup object
consolidation session is started after the specified backup session finishes. You can
view the progress of an automated object consolidation session in the Data Protector
monitor.
Interactive object consolidation session
An interactive object consolidation 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 consolidation
session. You may want to stop monitoring by disconnecting the user interface from
the session. The session will then continue in the background.
Object consolidation session data flow and processes
When an object consolidation 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 consolidation specification
for information on what to consolidate and which options, media, and devices
to use. It controls the object consolidation session.
