Intelligent Disaster Recovery (IDR) Restore
The purpose of this silent video is to give the Backup Exec user a look at how a restore using the IDR bootable ISO image works. For a full explanation of the IDR process, please refer to the IDR chapter in the Administration Guide.
In order to capture this video, the restore process is done on a virtual machine. This violates one of the conditions of using IDR (see document http://support.veritas.com/docs/320550). The restored machine would thus fail to boot up after the restore process is complete. I have done the same restore on a physical and the restored machine does boot up.
In the interest of saving time, I had excluded all the unnecessary data from the backup. Only the files that are necessary for a functioning system was included in the backup.
This restore was done using a backup and IDR created using Backup Exec 12.5. I recently upgraded to BE 2010 and repeated the test. Other than minor changes in some screens, the test remains the same.
Please note the following points of interest in the video
1 min. in – At this point, the network adaptors of the new machine will be presented. You will have to get at least one adaptor working in order to restore from a media server. If the driver for the adaptor of the new machine is different from that of the backed up machine, then you would need to inject the appropriate driver into the IDR bootable ISO image. The procedure to do so is given in document http://support.veritas.com/docs/337082.
2 min. in – At this point, you are given a chance to choose the .dr which points to the backup that you want to use for the restore. When you create the IDR bootable ISO image, the latest .dr file is included in the ISO image. If this image is created some time ago, you can at this stage point the restore process to the .dr file which corresponds to the backup that you want for the restore.
2.5 min. in – At this point, you have to use Disk Management to prepare the disks for the restore. That is, format them, etc. The restore process will just restore to the disks regardless of what is on them. Note that the disks on the new machine must be greater or equal in size to the disks that were backed up.
4.5 min. in – You would have to enter the Backup Exec Service Account into the prompt.
5 min. in – You would be presented with a list of resources to be restored. At the minimum, the C drive and the system state should be restored.
Beyond this, the restore process starts and the video can be uninteresting. When the restore is done, you would be prompted for additional .dr files for other things to be restored. Then the restore process will end with a re-boot.
You should also prepare the drivers for the hardware of the new machine so that when the restored machine boots up and detects the new hardware, you can feed it the appropriate drivers.
IDR is a good way to do disaster recovery and you should do a small test to experience it. I hope that this video would take some mystery out of the restore process.
