This article describes the CheckPoint Restart option in Backup Exec 10.x 11.x and 12.x and explains how to enable or disable it.
When this option is enabled, jobs that were interrupted because of a failover continue on the failover node from the point of interruption rather than starting over. Files that were already backed up are skipped, and only the remaining files in the job are backed up when the job is restarted. If this option is not selected, backup jobs are restarted from the beginning on the failover node.
CheckPoint Restart works best for the following file types:
1. NT file system (NTFS)
2. Generic Remote File System (GRFS)
3. Storage Management Services (SMS)
4. Exchange mailboxes and public folders
5. SQL database non-snapshot backups
The following types of files cannot use CheckPoint Restart:
1. System State
2. Lotus Domino
3. Exchange Information Store and Directory Services
4. GRFS Oracle
5. NTFS Image sets
6. NTFS Snapped volumes
7. SQL database snapshot backups
8. SQL transaction log backups
9. NetWare SMS (the checkpoint restart option should be disabled for NetWare backups
using the Remote Agent)
Checkpoint restart is not supported by the following:
1. The Advanced Open File Option.
2. The offhost backup feature in the Advanced Disk-based Backup Option.
3. When the option Collect additional information for synthetic backups is selected for the synthetic backup feature in the Advanced Disk-based Backup Option.
4. Incremental backups based on the archive bit.
1. On the navigation bar, click Backup
2. On the Properties pane, under Settings, click Clusters
3. Select or clear the Apply CheckPoint Restart (resume jobs from point of failover) check box
Defaults set in Backup Exec remain the same on the failover nodes as they were on the controlling node when failover occurs.
4. To apply Checkpoint Restart to backup jobs, make sure that the Error-Handling Rule for Cluster Failover is enabled.
Enable the Cluster Failover error-handling rule. On the Tools menu, select Error-Handling rules.
5. Select the Cluster Failover rule, and then click Edit
6. Verify that the Enabled field is selected
