HP Data Protector Operations Guide

Restarting failed sessions
You can restart a failed session or a completed session with failures after you have resolved
related problems. This restarts only the failed objects. The option can be used for clustered failed
objects as well.
You cannot restart failed sessions that are the result of an unsaved backup specification.
To restart sessions:
1. In the Context List, click Internal Database.
2. In the Scoping Pane, expand the Internal Database item and click Sessions.
3. A list of sessions is displayed in the Results Area. The status of each session is marked in
the Status column. Right-click a failed, aborted, or completed session with failures and
select Restart Failed Objects to back up the objects that failed.
Note: If the Cell Manager is setup with high availability clustering, and a failover of the Cell
Manager occurs during backup activity, the backup session will fail. The session can be restarted
automatically if this option is selected in the backup specification.
Resuming sessions
Using the Data Protector resume session functionality, you can resume backup and restore
sessions that failed for any of the following reasons:
• network problem
• fatal D
isk Agent problem
• fatal M
edia Agent problem
• fatal session manager problem
• fatal media problem (for example, torn tape)
• you aborted the session
However, first you have to resolve the problem.
When you resume a failed session, Data Protector continues the backup or restore in a new
session, starting where the failed session left off. The resumed session inherits all the options from
the original session.
However, not all session types can be resumed. Currently, Data Protector supports the following:
• Filesystem restore sessions
•
IDB restore sessions
• Data Protector Oracle Server integration backup sessions
• Data Protector Oracle Server integration restore sessions
