Backing Up a SIS Volume

Because SIS creates reparse points out of files that are identical, your backup program must understand this capability of the NTFS file system. The backup tool that is included with Windows 2000, Ntbackup.exe, handles these files properly.

If you are using a third-party backup solution, verify that it supports reparse points on an NTFS partition. If your backup program is not aware of SIS files, it might make duplicate copies of only the SIS files in the actual backup data file, so that when you restore these backup data files, they create normal files instead of the reparse points.
