The AddExcludeFiles method is used to explicitly exclude a file set (a specified file or files) that might otherwise be implicitly included when a component of the current writer is backed up.
Pointer to a null-terminated wide character string containing the root directory under which files are to be excluded.
The directory can be a local directory on the VSS machine, or it can be a file share directory on a remote file server.
UNC paths are supported.
The path can contain environment variables (for example, %SystemRoot%) but cannot contain wildcard characters.
There is no requirement that the path end with a backslash (""). It is up to applications that retrieve this information to check.
Pointer to a null-terminated wide character string containing the file specification of the files to be excluded.
A file specification cannot contain directory specifications (for example, no backslashes) but can contain the ? and * wildcard characters.
A Boolean value specifying whether the path specified by the wszPath parameter identifies only a single directory or if it indicates a hierarchy of directories to be traversed recursively. This parameter should be set to true if the path is treated as a hierarchy of directories to be recursed through, or false otherwise.
For information on traversing over mounted folders, see Working with Mounted Folders and Reparse Points.
The following are the valid return codes for this method.
| Value | Meaning |
|---|---|
|
The operation was successful. |
|
One of the parameter values is not valid. |
|
The caller is out of memory or other system resources. |
|
The XML document is not valid. Check the event log for details. For more information, see Event and Error Handling Under VSS. |
|
Unexpected error. The error code is logged in the error log file. For more information, see
Event and Error Handling Under VSS.
Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This value is not supported until Windows Server 2008 R2 and Windows 7. E_UNEXPECTED is used instead. |
Windows 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Windows XP and Windows Server 2003: Remote file shares are not supported until Windows 8 and Windows Server 2012. Writers support only local resources—sets of files whose absolute path starts with a valid local volume specification and cannot be a mapped network drive. Therefore, path inputs (wszPath) to AddExcludeFiles (after the resolution of any environment variables) must be in this format.
For example, it is often convenient to define a component to include all files in a given directory and then use AddExcludeFiles to explicitly remove some files (for instance, temporary files) from a backup.
