Data Domain: DD Boost: DDBMEXPTOOL does not delete expired data when -N is used

The backups are not all deleted even though they are expired,
When running DDBPEXPTOOL or the SQL job returns successful however not all backups are not deleted resulting in DD not getting cleaned up 
 

USE [master]
GO
DECLARE @returnCode int
EXEC @returnCode = dbo.emc_run_delete '-e "1 days ago" -k -n mssql -a "DDBOOST_USER = DDBOOST_USER" -a "DEVICE_HOST = DD_HOSTNAME " -a "DEVICE_PATH = /STorage_UNIT" -a "CLIENT = CLient_name" -N "BAckup_Name "'

ddbmexptool -k [-v -D 9 -b <start_save_time> -e <end_save_time> -N <save_set_name>] {-z <config_file> | -a "parameter=value"} -n <application>

When using the following command 

ddbmexptool -k [-v -D 9 -b <start_save_time> -e <end_save_time>  {-z <config_file> | -a "parameter=value"} -n <application>

Or the T-SQL without -N 

USE [master]
GO
DECLARE @returnCode int
EXEC @returnCode = dbo.emc_run_delete '-e "1 days ago" -k -n mssql -a "DDBOOST_USER = DDBOOST_USER" -a "DEVICE_HOST = DD_HOSTNAME " -a "DEVICE_PATH = /STorage_UNIT" -a "CLIENT = CLient_name" '

The expired data are deleted as expected. 

This is caused by the delete command filtering on the name of the backup and only deleting backup's which have the name -N "Backup_Name"'
-N specifies an exact match, not a partial match. So if you are specifying -N "Backup_Name" it ignores anything with a database name appended onto the end.

In the list command returning all the backup's made because did not add a saveset name filter.

USE [master]
GO
DECLARE @returnCode int
EXEC @returnCode = dbo.emc_run_delete '-e "1 days ago" -k -n mssql -a "DDBOOST_USER = DDBOOST_USER" -a "DEVICE_HOST = DD_HOSTNAME " -a "DEVICE_PATH = /STorage_UNIT" -a "CLIENT = CLient_name"'

Run the expiry tool or the Maintenance T-SQL Transcript without specifying the -N Parameter.

ddbmexptool -k [-v -D 9 -b <start_save_time> -e <end_save_time>  {-z <config_file> | -a "parameter=value"} -n <application>
