What issues does the new hotfix package address?
Issue 1
The DPM 2007 error logs are flushed only when the DPM service starts or stops. If the DPM service crashes, the DPM error logs are not flushed. This behavior causes some errors to be missing from the error logs.
Note After you apply this hotfix rollup, the DPM error logs are flushed every five minutes. The error logs are also flushed when the DPM service stops or crashes.
Issue 2
The DPM SQL Server database causes Microsoft SQL Server exceptions that are not captured in DPM traces.
Issue 3
Express full backup may take several hours to run if the DPM server is configured to protect more than 100 SQL Server databases.
Issue 4
The DPM administrator console does not open when multiple backup jobs concurrently access a tape library.
Issue 5
When library sharing is enabled, the GlobalDbConnectionString registry value may point to the local computer and not to the global SQL Server installation after a post-DPM 2007 Service Pack 1 rollup is installed.
Issue 6
A job may freeze before it transfers data if the DsRoleGetPrimaryDomainInformation function fails.
Issue 7
The DPM administrator console may not open if the Disconnect-DPMServer PowerShell cmdlet runs during a new tape backup job.
Issue 8
When DPM protects mirrored SQL Server databases that are clustered, the old volume bitmaps are not deleted. Therefore, the 128-volume bitmap limit may be exceeded.
