How to make a system restore point backup (shadow copy) out side my c:\\ partition for windows 7 ( plz don't say that can't be done ) ?

Move the volume shadow copy storage area to a different volume:

Caution: When you change the location of the shadow copy storage area, all previous shadow copies are deleted.

Note: To successfully create a shadow copy, at least one NTFS file system volume is required with at least300 MB of free space. Do not store the volume shadow copy storage area on a storage device that can be easily removed from the computer. Do not store the volume shadow copy storage area on a storage device that may not be available to Windows until late in the system startup sequence. For example, a logical unit number (LUN) created on an Internet SCSI (iSCSI) storage subsystem might not appear until a software initiator has started.

1. Click Start, and then click Computer.
2. Right-click any of the volumes listed, and then click Configure Shadow Copies.
3. Click the volume that is currently used for the volume shadow copy storage area, and then click Settings.

   Note: If shadow copies of the volume are enabled, you must first disable them by clicking the volume, and then clicking Disable.

4. Set the volume shadow copy area volume to a volume with more storage capacity by selecting the volume from the drop-down list under Storage area, and then click OK.
5. Ensure that the volume is still selected, and click Enable. If you are asked to confirm that you want to enable shadow copies, click Yes.
6. Click OK to exit.

To verify that the Volume Shadow Copy Service (VSS) can create a volume shadow copy, perform the following procedure, and then retry the previous VSS operation.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the VSS service can correctly create a volume shadow copy of the system volume:

1. Open an elevated Command Prompt window. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2. Type diskshadow, and then press Enter.
3. Type add volume <Volume>, where Volume is the drive letter for the system volume, and then press Enter.
4. Type create, and then press Enter.
