I have implemented the registry advocated here:

You can increase the number of maximum parallel online backup jobs from the default 8 to a configurable number using the following registry keys (if your underlying hardware and network bandwidth can support it).

The example below increases the limit to 12 jobs.

  • [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Azure Backup\DbgSettings\OnlineBackup]

"MaxParallelBackupJobs"=dword:0000000C

  • [HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Data Protection Manager\Configuration\DPMTaskController\MaxRunningTasksThreshold]

"6e7c76f4-a832-4418-a772-8e58fd7466cb"=dword:0000000CYou can increase the number of maximum parallel online backup jobs from the default 8 to a configurable number using the following registry keys (if your underlying hardware and network bandwidth can support it).

The example below increases the limit to 12 jobs.

  • [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Azure Backup\DbgSettings\OnlineBackup]

"MaxParallelBackupJobs"=dword:0000000C

  • [HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Data Protection Manager\Configuration\DPMTaskController\MaxRunningTasksThreshold]

"6e7c76f4-a832-4418-a772-8e58fd7466cb"=dword:0000000C

but am still getting the exceed limit of 8...I have 11 tasks and increased the registry value(s) to 12...wondering why?

    @Brandt Smith Thank you for contacting us on Microsoft Q&A platform. Happy to help!

    The registry setting seems to be fine as you have added the registry to run the 12 online backup in parallel. Request you to please provide the MABS version which you currently are using as this setting will only apply to latest MABS server which is MABSv4.
