Solution

1. Stop NetBackup services on the client.

• Open Windows Command Prompt with "Run As Administrator"
• Change directories to: install_path\NetBackup\bin\
• Run command: bpdown -v -f
• Verify all NetBackup processes are stopped by running: bpps.exe
• If there are still running NetBackup processes, such as bpfis.exe, terminate them manually.

2. Delete the NTFS change journal for each problem drive letter, or disk volume:

• For each drive letter, or disk volume, run the following commands:
  • Go to a command prompt and query the USN Change Journal using command:
    • fsutil usn queryjournal <drive letter:>
  • To delete the NTFS journal, run the following command:
    • fsutil usn deletejournal /D <drive letter:>
  • For example using the C: drive:
    • fsutil usn deletejournal /D C:
• Also, remove the three Veritas NetBackup Change Journal database files on the root of the related drive letter, or disk volume.
  • For example using the C: drive:
    • C:\VxCJinfo.dat
    • C:\VxCJdelete.dat
    • C:\VxCJmon.dat

3. Start NetBackup services on the client:

• Open Windows Command Prompt with "Run As Administrator"
• Change directories to: install_path\NetBackup\bin\
• Run command: bpup -v -f
