NetBackup offers support for the Microsoft change journal to enhance performance of incremental backups on supported Windows OS levels. By enabling the Use change journal in incrementals check box, NetBackup can provide faster incremental backups for NTFS 5 (and later) volumes that store large numbers - possibly millions - of files. Use change journal in incrementals is available only when a valid tracker database exists on the applicable volumes. The default is not enabled.

When this property is enabled, it automatically enables the Incrementals are based on timestamp property.

The Microsoft change journal is a disk file that records and retains the most recent changes to an NTFS volume. By monitoring the change journal, NetBackup can determine which file system objects have changed and when. This information is used to shorten the discovery process that NetBackup performs during an incremental backup by making a file system scan unnecessary.

See How to determine if change journal support is useful in your NetBackup environment.
