Issue



Exclusion statements in the backup selection list against a NetApp (or IBM) filer will cause the job to not backup the expected total amount of data.


Solution




If the backup selection list for resources located on a NetApp or IBM filer (running Ontap 7.x) contains /EXCLUDE statements that were created by de-selecting folders then the backup job will not backup all the selected data, but will indicate that the job has completed successfully. The byte count against the job will report as significantly less than the expected byte count against the selection list.

The /EXCLUDE statements can only be seen by selecting the "View Selection Details" tab in the selection list which provides a text based listing of the selection list.  An image showing an example of a /EXCLUDE statement can be seen in Figure 1.

As well as the reduced byte count the Job Log will show a couple of entries in the NDMP Log section that confirm the issue is present, these entries are a line stating "NDMP Log Message: DUMP: Using Partial Volume Dump with Exclude Lists" in combination with an entry in the "NDMP Environment" section stating "EXCLUDE=*.*,*.*,*.*" Note: the number of *.* entries in this message will vary depending on how many folders were de-selected. An example of these log entries can be seen in Figure 2.

A secondary cause has also been identified where custom entries containing wildcard characters (such as *.*) have been added to the Global Exclusion List in the  Backup Exec Console. The Exclusion List can be seen by selecting Edit --> Manage Selection Lists..., selecting Excludes and clicking on the Edit button.
 
SOLUTION
 
A fix for this issue is now available in Service Pack 2 for Backup Exec 12.5 for Windows Servers and it can be downloaded from the link mentioned below.
