Changing the Compression Level of an Existing MirrorYou can modify the following settings through the Mirror Properties dialog:• Compression Level - specifies the compression level for the given mirror. The value can be set fromlowest to highest. We recommend a level of "Medium low", but users should test several differentsettings to see what level works best in their specific environment. Compression is typically notrequired for LAN connections > 100 Mbps.Note: Any changes made to the compression level setting are automatically propagated to all thesystems listed in the Mirror Properties display.• Maximum Bandwidth - Specifies the maximum amount of network bandwidth (in kilobits per second)that a particular mirror is allowed to use. A value of 0 means unlimited.Note: In a multi-target configuration where A is mirroring to B and C, the properties of the mirror between Band C cannot be set until B or C becomes the source.Changing the Compression Level of an Existing MirrorThe compression level of the mirror is set during mirror creation and applies to that specific mirror only.To change the compression level of an existing the mirror, edit the properties of the mirror from within theDataKeeper GUI.1. Select the mirror and click on Edit.2. Change the compression level by dragging on the slider button.The values change from lowest to the highest. We recommend a level of “Medium low”, but users should testseveral different settings to see what level works best in their specific environment.Also note that by changing the parameter as the comment suggests in the dialog, the compression propertieswill be propagated to all the systems listed in the Mirror Properties display.DataKeeper for Windows Technical DocumentationPage 117
