Use native Change Log Provider

This option was introduced with Data Protector 6.1. If selected, enhanced incremental backup

will be performed using the Change Log Provider (if it is available). Currently the Change Log

Provider is only available for the Windows NTFS File System and is based on the Windows

Change Journal Provider.

The Change Log Provider generates a list of files that have been modified since the last backup

and does not perform a file tree walk.

Note: On Windows Vista and Windows Server 2008 the Change Journal is active by default.
