Backup

Managing Failed Backups

If a backup of an object fails to start, Data Protector tries to back up this object again at the end of the backup session. If it fails again, the object is not backed up, and the status of the object and the session is set to Failed. A backup is repeated when it is scheduled. If some objects finish properly, the session status is completed with failures.

Clients that are not up and running when they are scheduled to be backed up are retried after the rest of the objects are completed. Before the first failed object is retried, the backup session is suspended for 30 seconds. This waiting time can be changed using the WaitBeforeRetry global option. See “Global Options File” on page 523 for information on how to change global options.

If you have an infrequent backup schedule, this may result in a period of time when there is no recent backup of your data.

Data Protector always needs one full backup of data. If no protected full backup is available, a full backup will be done next time, even though an incremental backup was scheduled. To avoid this, run a full backup of the failed system interactively before you schedule a backup.

For details on full and incremental backup behavior, see the HP OpenView Storage Data Protector Concepts Guide.

When you configure a backup, you can use the Reconnect Broken Connection option. When this option is set, Data Protector reconnects the Backup Session Manager and Disk or Media Agents in the case of short-term network problems during a backup session. This often happens on unreliable LAN networks.

Enabling Wake ONLAN Support

If you have any machines that support remote power-up (Wake ONLAN), you can use the Data Protector Wake ONLAN support. When a Backup Session Manager fails to connect to a client that is configured to use Wake ONLAN support, it sends a wake-up request according to the Wake ONLAN protocol, and retries connecting to the client. This allows the full use of the power-saving features of desktop systems, which would otherwise interfere with the backup process.
