Incremental backup job is copying data that is unchanged when backing up network shares and using the Microsoft Change Journal (Using modified time)


Incremental backups incorrectly copy the data that is unchanged when backing up network shares. This problem occurs when using the Microsoft Change Journal (Using modified time instead of Using archive bit) to identify which files where modified since the last backup. The Microsoft Change Journal cannot be used to accurately identify modified files for network shares. As a result, Backup Exec conducts a full backup each time an incremental backup job is performed.


Do not use the Microsoft Change Journal (Using modified time) for any jobs that back up network shares. Instead, when creating the backup job, select a backup method that uses the archive bit to identify modified files.
