SisCreateBackupStructure function
The SisCreateBackupStructure function creates a SIS backup structure based on the supplied information.
Syntax
BOOL SisCreateBackupStructure(
_In_ PWCHAR volumeRoot,
_Out_ PVOID *sisBackupStructure,
_Out_ PWCHAR *commonStoreRootPathname,
_Out_ PULONG countOfCommonStoreFilesToBackUp,
_Out_ PWCHAR **commonStoreFilesToBackUp
);
Parameters
-
volumeRoot [in]
-
File name of the volume root, without the trailing backslash, of the volume to be backed up. For example, specify "C:" and not "C:\".
-
sisBackupStructure [out]
-
Returned SIS backup structure.
-
commonStoreRootPathname [out]
-
Fully qualified path name of the specified volume's common store. For example, "c:\SIS Common Store".
-
countOfCommonStoreFilesToBackUp [out]
-
Number of files listed in the commonStoreFilesToBackUp parameter.
-
commonStoreFilesToBackUp [out]
-
Pointer to an array of file names that specifies a list of internal files used by SIS to manage the specified volume. These files should be backed up at the same time and in the same manner as the common-store files requested by SisCSFilesToBackupForLink
Return value
This function returns TRUE if it completes successfully and FALSE otherwise. Call GetLastError to get more information about the reason the call failed.
Remarks
This function creates a SIS backup structure, which is used by the SIS backup API to create and maintain a list of the file links on the volume and the original files the links point to. This function should be called only once for each SIS-enabled volume being backed up. All files within the specified volume should be treated as common-store files and backed up only if SIS indicates that they should.
The countOfCommonStoreFilesToBackUp and commonStoreFilesToBackUp parameters together return a list of files that must be backed up regardless of which links are backed up.
If countOfCommonStoreFilesToBackUp is 0, commonStoreFilesToBackUp may be a NULL pointer. The value of the commonStoreFilesToBackUp parameter should be ignored.
After the backup operation is complete, deallocate the memory used by the commonStoreFilesToBackUp array of strings by calling SisFreeAllocatedMemory.
