When you create a backup job and select the "dump" backup type, you can select specific files and directories that you do not want to include in the backup job.
To exclude directories and files from an EMC backup selection
Select the resource that contains the files you want to exclude from the backup selection.
Use one of the following methods to select the file system where the file or directory you want to exclude is located:
Under Resources, navigate to the file system.
Backup Exec automatically fills in the File system text box with the name of the EMC Celerra Server and the file system that you selected.
Under Resource selection, in File system, type the path for the file system if it is not already filled in..
//EMC_Celerra_Server_name/file_system_name
For example, type "//emcnas_ndmp/fs_1" to indicate an EMC Celerra Server named "emcnas_ndmp" and a file system named "fs_1".
