Cause

In the bptm log snip above, "error=665" is a native Microsoft Windows error which indicates, "The requested operation could not be completed due to a file system limitation"

Upon investigation, NTFS compression was enabled on the volume housing the Basic Disk storage unit.

 

Solution

The solution is to disable NTFS compression on the volume housing the Basic Disk Storage Unit.

In the example above, the backup was large in nature, creating a fragment on the Disk Storage Unit in excess of 30 GB in size.  Once the fragment was fully written to disk, the NTFS file-system began compression of the file.  Although the initial "write" operation to the fragment was complete, NetBackup, was still performing follow-up write operations on the image fragment to conclude the backup job.  The fragment was not accessible because it was taking a long time to compress.  This caused the backup job to fail.
