Can't Open File : Shadow Copy Components

[Braker19]

Below is a snip-it from the activity log, I'm running netbackup 7.5.  I use DFS to replicate, and I set shadow copy comments for the backup selection list.  I'm not sure if this is a problem with DFS shadow copy components or if it's the open file manager.  I applied a lic for open file manager.  Most of the data is backed up on ther server but i receive a warning operation was partially successful

Summary:
DFSR backups may complete with Status 1 due to insufficient space in the Shadow Copy Storage Area, or high disk I/O.

Troubleshooting:
Examine the bpbkar log on the client:

Examine the Windows System Event logs on the client:
Event Type: Error
Event Source: VolSnap
Event Category: None
Event ID: 25
Description:
The shadow copies of volume VolumeName were aborted because the diff area file could not grow in time. Consider reducing the IO load on this system to avoid this problem in the future.


Resolution:
Increase the amount of storage space available for Shadow Copies within the drive properties or change the Shadow Copy storage area location to another drive with sufficient space or less I/O.
