Copying objects

What is object copy?

The Data Protector object copy functionality enables you to copy selected object versions to a specific media set. You can select object versions from one or several backup sessions or object consolidation sessions. During the object copy session, Data Protector reads the backed up data from the source media, transfers the data, and writes it to the target media.

The result of an object copy session is a media set that contains copies of the object versions you specified.

Figure 31 on page 114 shows how data backed up at a specific point in time can be copied afterwards. You can copy any backup object from a medium containing a backup or a medium containing a copy of the object.
