DPM2010: Data corruption detected during read (3129)

Microsoft.Windows.SystemCenterDPM2010.DataCorruptionDetectedDuringRead (UnitMonitor)

DPM has detected an inconsistent replica of the data source during the backup. This is because of an IO error on a protected server with possible hardware issues.

Knowledge Base article:

Summary

DPM has detected data inconsistency during the backup of this data source.

Causes

The likely causes are:

IO error on the protected computer
Hardware issues on the protected computer

Resolutions

Review the system event log of protected computer for any hardware-related errors, and rectify them.

Run hardware diagnostic tools to verify health of the hardware.

Run application specific integrity checks to ensure logical consistency of data. In case of failure, recover the data from last recovery point and perform application specific integrity check. Repeat the process with previous recovery points till a logical consistent recovery point is recovered.

Create new recovery points manually for the data source indicated in the error.

Run integrity check more frequently.
