This topic describes advanced data management settings for dSources.

When linking a dSource, you can use custom data management settings to improve overall performance and match the needs of your specific server and data environment. If no specific settings are required, leverage default data management settings.

Accessing Data Management Settings

There are three ways to set or modify data management settings for dSources:

  1. During the dSource linking process, click Advanced in the Data Management panel of the Add dSource wizard.
  2. On the back of the dSource card, click the field next to Retention Policy under Data Management. Click the Edit icon.
    For SnapSync and Retention policies, click the policy name. This will open the Policy Management screen.
  3. Select Manage > Policies in the top menu bar. 
    This will open the Policy Management screen. Select the policy for the dSource you want to modify, and click Modify. 
    For more information, see Creating Custom Policies and Creating Policy Templates.

Retention Policies

Retention policies define the length of time Delphix Engine retains snapshots and log files to which you can rewind or provision objects from past points in time. The retention time for snapshots must be equal to, or longer than, the retention time for logs.

To support longer retention times, you may need to allocate more storage to the Delphix Engine. The retention policy – in combination with the SnapSync policy – can have a significant impact on the performance and storage consumption of the Delphix Engine.

Benefits of Longer Retention 

With increased retention time for snapshots and logs, you allow a longer (older) rollback period for your data. 

Common use cases for longer retention include:

  • SOX compliance

  • Frequent application changes and development

  • Caution and controlled progression of data

  • Reduction of project risk

  • Speed of rollback / restore to older points in time

With logsync enabled, you can customize both the retention policy and the SnapSync policy to access logs for longer periods of time, enabling point-in-time rollback and provisioning.
