SUMMARY
When you install Remote Installation Service (RIS) on a
computer, you also set up Single Instance Storage (SIS) on a volume of the hard
disk drive. SIS reduces the amount of space in a volume that data uses by
removing duplicate files and placing them in a common store directory (\Sis
Common Store), which is a hidden directory in the root directory of the volume.
When you run Risetup.exe to complete the installation of RIS, you choose an
NTFS file system volume on which to store your images. You install the SIS
filter on this volume.
When you restore a volume that is managed by
SIS, you must follow specific steps to prevent corruption of the data you are
restoring. Also, because SIS manages the entire volume, not just the RIS
directory structure, SIS will manage any data that you place on this
volume.
Note: To successfully restore a SIS-managed volume, the SIS/Groveler
must be running and attached to the volume to which you are restoring data. If
it is not, any non-SIS-linked files will still be accessible, but SIS-linked
files will not be accessible, and they will appear to be corrupted. The name
and size of a SIS-linked file will appear as normal. However, the file will be
a zero-length file because it will not have access to the data it should
contain.

To make SIS Management available on your computer
Select one of the following methods to make SIS management
available for a volume on your computer based on whether your computer is
running RIS.

Remote Installation Services is installed on the computer
The following instructions explain how to start RIS and the SIS
service, and how to create the basic RIS directory structure. As a result, the
directory will be empty and ready for you to begin restoring the data from
backup using your backup program.
If your computer is running RIS,
and you are restoring
only the volume in which RIS images were stored, (due to disk drive
failure, installation of a larger had drive, or similar circumstances), follow
these steps:
- Install the hard drive and format it using the NTFS file
system.
- Create a volume with the same name as the one you are
restoring that resides on the same letter drive. Trivial FTP Daemon (TFTPD)
hard codes the drive letter of its Trivial File Transfer Protocol (TFTP) root
in its registry key.
- From a command prompt, type risetup
-check, and then press ENTER.
- Follow the instructions on the screen. When you are asked
for the RIS volume, type the name of the volume you are restoring (the volume
you created in step 2).
- Using NTBackup or your backup program, restore the RIS
volume from the backup media.

Remote Installation Services is not installed on the computer
Note: You need to copy an image from the Windows 2000 Professional
CD-ROM during the following procedure. Be sure you have the CD-ROM
available.
If RIS is not installed on the system because the server
is being rebuilt, or the images are being moved to a new server, follow these
steps:
- Install RIS using Add/Remove programs, and
then restart the computer.
- Using Disk Management, create a volume large enough to hold your RIS images. The
minimum recommended size is 2 gigabytes (GB).
- Restart the computer, and from a command prompt, run
Risetup.exe.
- Follow the instructions on the screen. When you are asked
for the name of the volume that will hold the RIS images, type the name of the
volume you created in step 2.
When you have completed the preceding steps to install and
start RIS and attach the SIS/Groveler to the volume, you can begin restoring
the data from backup using your backup program.

Troubleshooting
Your backup program does not need to understand SIS-linked files
but it should understand NTFS file system reparse points. If you are using a
non-Microsoft backup program, check with the vendor to see if your program has
this capability.
When you install SIS, you also install Sisbkup.dll.
Your backup program can call this DLL when backing up or restoring a
SIS-managed volume so that the data is handled properly. You must modify your
backup program to call this DLL.
If your backup program does not call
Sisbkup.dll, your program will back up all of the data on the volume, the data
will require more storage space on the tape than it uses on the volume, and
when you restore the volume from the tape, the files will be restored as
non-Sis-linked files.
