Tivoli Storage Manager for Windows Backup-Archive Clients Installation and User's Guide
To perform an image restore (offline or online) you must have
administrative authority on the system. You can use the following
procedure to restore an image of your file system or raw logical volume:
- Click Restore from the main window. The Restore window
appears.
- Expand the directory tree.
- Locate the object in the tree named Image and expand it.
Click the selection box next to the image you want to restore.
- To modify specific restore options, click the Options button
located to the right of the Estimate button. Any options you
change are effective during the current session only.
- Click Restore. The Restore Destination window
appears. The image can be restored to the volume with the drive letter
or mount point from which it was originally backed up. Alternatively, a
different volume can be chosen for the restore location.
- Click the Restore button to begin the restore. The
Task List window appears showing the progress of the
restore. The Restore Report window displays a detailed status
report.
When performing an image restore, consider the following:
- Restoring the image of a volume will restore the volume to the same state
that it was in when you performed your last image backup. Be absolutely
sure that you need to restore an image, for it will replace your entire
current file system or raw volume with the image on the server.
- Ensure that the file system or volume to which you are restoring the image
is at least as large as the image that is being restored.
- The file system or volume you are restoring to does not have to be the
same type as the original. The volume does not even have to be
formatted. The image restore process will create the appropriately
formatted file system for you.
- Ensure that the target volume of the restore is not in use. The
client will lock the volume before starting the restore. The client
will unlock the volume after the restore completes. If the volume is in
use when the client attempts to lock the file system, the restore will
fail.
- You cannot restore an image to where the Tivoli Storage Manager client
program is installed.
- If you created an image of the system drive, you cannot restore the image
to the same location because the client cannot have an exclusive lock of the
system drive. Also, because of different system component
configurations, the system image may not be consistent across components (such
as Active Directory). Some of these components can be configured to use
different volumes where parts are installed on the system drive and others to
non-system volumes.
- If you have run progressive incremental backups and image
backups of your file system, you can perform an incremental image restore of
the file system. The process restores individual files after the
complete image is restored. The individual files restored are those
backed up after the original image. Optionally, if files were deleted
after the original backup, the incremental restore can delete those files from
the base image. Incremental backups and restores can be performed only
on mounted file systems, not on raw logical volumes.
- Note:
- If for some reason a restored image is corrupted, you can use the
chkdsk tool to attempt to repair the image.
