Dell NetWorker 19.9 Administration Guide

Configuring checkpoint restart

To allow a failed backup for a client to restart from a known good point, you must enable checkpoint restart for the NetWorker Client resource and configure the number of automatic retries for the backup action in the data protection policy.

1. In the Administration window, click Protection.
2. From the View menu, select Diagnostic Mode.
3. In the expanded left pane, select Clients.
4. Right-click the client resource and select Properties.
   The Client Properties dialog box appears.
5. On the General tab, select the Checkpoint enabled checkbox.
6. From the Checkpoint granularity list, select whether to restart the backup from the point of failure at the directory or file level:
   • Select Directory to restart the backup at the directory level. After each directory is saved, the data is committed to the media and index database. If a directory contains a large number of entries, intermediate checkpoints are created.
   • Select File to restart the backup at the file level. Use this option only for save sets with a few large files. Committing every file to the index and the media database is time consuming. Performance degradation may occur for backups that contain many small files.
7. Click OK on the Client Properties dialog box.
8. Configure the number of times to retry a failed backup:
   1. In the expanded left pane of the NetWorker Administration window, select Policies.
   2. Select the policy.
   3. In the right pane, select the Actions tab.
   4. Right-click the action and select Properties.
      The Policy Action wizard appears.
   5. On the Advanced Options page, perform the following tasks:
      1. In the Retries box, specify the number of retries that should occur if the backup fails.
      2. In the Retry Delay box, specify a delay in seconds before a failed backup is retried.
      3. Click Next.
   6. On the Action Wizard Summary page, review the settings for the backup action, and then click Configure .
