The following table provides troubleshooting guidance for Windows Server Backup (WSB) issues.

Windows Server Backup Issues


Issue Possible Cause Resolution

When using WSB, the following errors might occur:

  • DPM has detected a discontinuity in the log chain for <DatasourceType> <DatasourceName> on <ServerName> since the last synchronization.

  • The recovery to the latest point in time failed. During a recovery to the latest point in time, DPM attempts to perform a SQL Server transaction log backup to receive the latest changes from the SQL Server database <DatasourceName> on <ServerName> before starting the recovery. This transaction log backup has failed.

  • DPM attempted to perform a SQL Server log backup, either as part of a backup job or a recovery to latest point in time job. The SQL Server log backup job has detected a discontinuity in the SQL Server log chain for <DatasourceType> database <DatasourceName> since the last backup. All incremental backup jobs will fail until an express full backup runs.

Performing backups using WSB on a server which DPM is protecting can interfere with the backups DPM uses.

If you are using WSB, do the following:

  • Ensure that WSB always takes a COPY backup using the WSB Backup Once Wizard.

  • If you are using WSB Scheduled Backups, ensure that the volumes you are backing up do not contain any application data such as Exchange Server data or SQL Server data.

  • After you reconfigure WSB, on the DPM server, run a new express full backup.
