Secondary DPM 2010 limits RRS feed

  • Question

  • I'm getting the following message when creating secondary protection groups:

    "The maximum number of diaster recovery data sourcs that a DPM server can protect is 300. If you exceed this limit, DPM server will miss its backup SLA and eventually become unresponsive"

    The recommendation is to reduce the number of DR data sources.  How is this limit determined? And is it accurate? 

    From what I've read, the primary can protect over 2000 databases as long as space and volume limits are not maxed.

  • The number of protected datasources and retention range ultimately depends on how many recovery points you can have on a DPM server and then how many times the replica or recovery point volumes can be expanded if needed. This is because of the limitation in LDM of 2960 (see info from Ruud in this post http://social.technet.microsoft.com/Forums/en-US/dpmfilebackup/thread/1f97d270-b702-4cc5-8df2-e7807e97ba9a/)

    If the number of datasources protected are not colocated (for those that support colocation) then each datasource will use a separate replica and recovery point volume and be treated as a separate datasource and this will impact the RP retention you can have. You would need to co-locate SQL databases to get close to the 2000 databases that have been touted so that you did not exceed the 300 datasources in DPM.
