Specifies the path to the DHCP backup file. The following table summarizes the attributes of the BackupPath property.
| Attribute | Value |
|---|---|
| Data type | Null-terminated Unicode string |
| Access | Read/write |
| Status | Required |
| Structure | CLUSPROP_SZ |
| Maximum | None (but see Maximum Property Size.) |
| Default | The DHCP BackupPath property defaults to a value of the form drive:\old path where drive is the drive letter of the Physical Disk dependency and old path is the former path to the DHCP backup file. For example, if a DHCP Service resource depends on drive K: and the former path was C:\WinNT\System32\dhcp, the default for this property will be K:\WinNT\System32\dhcp. |
Remarks
The DHCP backup path does not include a file name or a trailing backslash.
The CLUSPROP_SZ_DECLARE macro creates a CLUSPROP_SZ structure with an array of the correct size.
Examples
The property value portion of a property list entry for BackupPath can be set with the following example code.
WCHAR szBackupPathData[] = L"\\\\DHCP\\BackupDirectory";
CLUSPROP_SZ_DECLARE( BackupPathValue,
sizeof( szBackupPathData ) / sizeof( WCHAR ) );
BackupPathValue.Syntax.dw = CLUSPROP_SYNTAX_LIST_VALUE_SZ;
BackupPathValue.cbLength = sizeof( szBackupPathData );
StringCbCopy( BackupPathValue.sz,
BackupPathValue.cbLength,
szBackupPathData );
