Resolving error code 1296 during Exchange backups

Brien Posey explains how to resolve a common error code when using VSS-based backup software for Exchange backups.

What is one common Exchange VSS writer issue users could encounter when backing up Exchange databases with VSS-based backup software?

One of the most common Exchange-related VSS errors is error code 1296, which states, "Exchange VSS Writer Failed with Error Code 1296 when preparing components (databases) for backup." This problem occurs as a result of having circular logging enabled.

You can disable circular logging by opening the Exchange Management Shell and entering the following command:

Set-StorageGroup -Identity "First Storage Group" -CircularLoggingEnabled $false
