IBM Rescue and Recovery with Rapid Restore is a one-button solution that includes a set of self recovery tools to help users diagnose, get help and recover from a software crash, even if the primary operating system will not boot. It helps with everything from complete software failure to occasions when you need only to restore a corrupted or deleted file. However it does not have the ability to save and restore the master boot record or partition tables on the hard drive. If those file sectors are damaged it is not possible to read the hard drive thereby making recovery impossible. The next version of Rescue and Recovery (RnR) will add master boot and partition table recovery to the product. Although there is much previous art on saving MBR records this invention is how to automate the decision flow so the user does not have to understand the details of what a MBR is and make the difficult if not impossible decision on what to do

Rapid Restore Recovery Flow

There are two things stored in the "first sectors" of the hard drive:

MBR (code that is needed to boot the device)



If either is damaged the bios can't read the hard drive. If you can't read the drive you can't recover your backup files or restore your image. Most users don't understand how hard drive work and explaining what a master boot record or partition and what you need to do is beyond the scope. Without an MBR and partition table the BIOS acts like there is no drive present and will not even get to the setup screens.

1) We add to RnR the ability to store MBR and partition table during each system backup to a device different than the hard drive. It can be a network drive, secondary drive, USB key, CD, flash, etc.
2) This location is stored in system bios or can be stored on a removable media which the bios will look for during recovery.

Now user needs to recover.

First we need to determine if the user is attempting to fix/restore their existing drive? If yes - follow flow chart below. This flow will automatically determine if the MBR and partition table are OK.

If not, it will attempt a fast recovery which is just replacing MBR and partition table from stored location contained in BIOS. If only the MBR is damaged this will fix the problem very quickly. It also has the advantage that work saved since last backup save is not lost.

If it can read the drive than a full image recovery is attempted (current process).
