Change Journal Operations

Fsutil usn

An Update Sequence Number (USN) Journal is a change journal of file and directory changes on the NTFS volume

including a description of the change, and the name of the file or directory. Each log file is incremented for each

entry in the journal. Log files are stored until they are deleted or storage runs out. If storage is exhausted, older log

files are deleted and cannot be restored.

If too many file or directory changes are encountered on your Windows Server, you may encounter a max journal

wrapping error causing slower Barracuda Backup Agent backups. While full backups should not be affected, you

may encounter differential and incremental backup failure:

Deleting an Active USN Change Journal

Use the following steps to remove the active USN change Journal using .fsutil usn deletejournal

The following instructions apply only if the USN change Journal is available and readable.

fsutil usn Parameters

deletejournal - Deletes the active USN change journal. Deleting the change journal impacts the File Replication Service

(FRS) and the Indexing Service. Additionally, this negatively impacts FRS SYSVOL replication and replication between DFS

link alternates during rescanning of the volume.

/D - Disables the active USN change journal and returns I/O control while the change journal is being disabled.
