A Rescue Image is a recoverable image of a protected machine that can be saved to any type of storage; NAS, USB, removable disks. The Rescue Image can be restored directly to the failed machine with the use of a Replay Recovery Console, which is launched from an ISO created with the Replay Boot CD Builder. Rescue images can be continuously updated when Recovery Points are updated, enabling additional protection from a server failure.
To create a Rescue Image for a protected server:
1. From the Admin Console, click on the protected server in the tree and then click the Rescue Image hyperlink in the Control Panel of the Summary tab.
2. Enter a folder to store the files created for the Rescue Image. Click Next.
3. Check the “Keep the rescue image updated with the latest recovery point” box to continuously update the Rescue Image. Enter how often the image should be updated. Also, select one of the radio buttons for the start date/time – either immediately when a new Recovery Point is created, or suspend until some time in the future. Click Finish.
There will be a status message showing to the right of the Rescue Image link. If keep updated was selected, it will first say “Waiting for next recovery point“. When the rescue image is being created, the status will say “Exporting full snapshot as of [date/time] to [export location]“
If a status message does not appear, or if there is initially a status message and then none, check the Events tab for the Core to see if there are any errors reported that may have been created during the attempt to export.
The export can be stopped by clicking the Stop… button. The current export or current and future exports can be aborted.
The files exported to the folder will be of the following types:
- recoverypoint.xml - this is the file that will be opened from the RRC when opening the rescue image.
- vmdk’s for each volume exported from the recovery point.
To restore with the Rescue Image, do the following:
1. Start the Replay Recovery Console (ISO created with Boot CD Builder). For more information on the RRC and Boot CD, please see Restoring a Server from Bare metal from a Replay Core.
2. Click the Import Recovery Point button. The RRC Disk Imager will display, and present a dialog to select the recoverypoint.xml file (created as part of the Rescue Image).
3. Browse to the recoverypoint.xml and click Open. The RRC Disk Imager windows displays where the Rescue Image volume will be mapped to the disk on the bare metal machine. Right click on each disk in the Volume Images Available for Recovery area, and select a Destination Disk. Do this until all disks to restore are mapped.
4. Make one of the Destination disks bootable. To do this right-click on a Destination disk and select Make Bootable.
Note: If the protected server being restored has an SRP as in the case of 2008 R2 or Windows 7, map the SRP to a disk, and make that disk the one that is bootable.
5. Once all the disks are mapped and one is marked as bootable, click on Save and Apply Changes in the upper right corner.
6. Remove the CD and click the Reboot button on the RRC to reboot the machine.
