Ocster Backup Rescue Disc

The rescue system is intended for two kinds of situations:

  1. To restore a backup to your main hard disk. This cannot be done while your normal system is running, so you need the rescue system for that.

  2. To restore a backup when your system is so damaged that it does not start anymore.


Downloading the rescue system data

The rescue system can be created either as a CD or as a USB stick. The initial steps are the same for both options:

  1. Download the rescue system data (ZIP file):

    Download

    If you have a very old computer (from the year 2009 or before) or a computer without a 64 bit processor then please download the following version instead:
    Download for old computers and 32 bit computers

    The current version number of the rescue system is v1.35.

  2. Extract the downloaded file (ocster_rescue_disc_archive) by right-clicking on it and selecting "Extract All". Then follow the instructions in the window that opens to actually extract the data.

    If the option "Extract All" is not shown on your computer then try to double-click on the downloaded file. This will probably open a program that allows you to extract the file.

    If double-clicking does not open an extraction program then you will have to install a free ZIP software to extract the data (for example WinRAR).

  3. After you have extracted the ZIP file you should now have a file called "ocster_rescue_disc.iso". It contains the rescue system data.

  4. The next steps depend on wether you would like to create a CD or a USB stick.


Rescue CD

You should follow these instructions only if you want to create a rescue CD. See below for instructions to create a USB stick.

Burn the downloaded ISO file (see above) to a CD. It is very important that you use a burning function that specifically mentions that it is intended for ISO files or disc images. Do not simply burn the downloaded file as a normal file to the CD. Then the CD will not work.

Windows 7 or higher: You can usually simply right-click on the file in Windows Explorer and select "Burn disc image" from the menu.
If this menu entry is not shown on your computer then please follow the instructions below for "older versions of Windows".

Older versions of Windows: You can download a free burning software that burns the CD in the correct way from here:
Download burning software


Rescue USB Stick

You should follow these steps only if you want to create a rescue USB stick. See above for instructions to create a CD instead.

  • To create the USB stick you need the free software "Unetbootin". You can download it here:
    Download Unetbootin

  • Start the downloaded software.

  • Select the option "Diskimage".

  • Click on the "..." button to the right of the "Diskimage" option. Select the ISO file that you extracted before (see above).

  • At the bottom of the window: select the drive letter of the USB stick that you want to use.
    WARNING: The current contents of the selected drive will be deleted if you continue!

  • Click on "OK"

  • The USB stick is now being created.
