DFM Performance Data - limiting scope?

Greetings!

We've noted that the folder that DFM/Ops Manager uses for Performance Data (\DFM\Perfdata) is increasing.  This appears to be causing some pressure when performing DFM database backups (i.e. the Database backup itself is 3.6 GB, but the backup job needs 10.2 GB to process).  This appears to be related to the size of the \perfdata folder (e.g. 13.3 GB)

Is there an option to configure in DFM to limit the history of performance data retained?  For example - I'd like to keep only 4-6 weeks of historical performance data for analysis.  I didn't really see any configuration options that would allow me to limit the performance data collection in this way.

Thanks in advance for any suggestions or tips!

Hi Jeff,

>> Thanks Richard - that was my concern that the retention was a global parameter change, not one I could adjust for performance advisor only.

Change in retention period with 'dfm perf data modify' affects only performance advisor data,  it has NO impact on Operations Manager (OM) reports, graphs related data.

However following reports available with OM web UI will have impact as these reports are specific to performance advisor.

  storage-system-performance-summary performance summary of storage system
  storage-system-NAS-performance-summary NAS performance summary of storage system
  storage-system-SAN-performance-summary SAN performance summary of storage systems
  aggregates-performance-summary performance summary of aggregate
  volumes-performance-summary performance summary of volume
  volumes-NAS-performance-summary NAS performance summary of volume
  volumes-SAN-performance-summary SAN performance summary of volume
  qtrees-performance-summary performance summary of Qtree
  luns-performance-summary  performance summary of LUN
  disks-performance-summary performance summary  of Disks
  vfiler-performance-summary performance summary of vFilers

Please let me know if I can provide more details on this.
