The DVD4.iso will be available in the Linux Live CD directory of the Calypso Installer package. You can also download the DVD4.iso.

  1. Log on to the Maintenance Advantage web site.

  2. Click the Downloads & Packages tab to download the DVD4.iso.

Similar System Restore

If you are restoring to a computer which has the same hard disk configuration as that of the backed up computer, perform a Similar System Restore using one of the following methods:

Non Interactive Restore

A recovery point is a point-in-time configuration of the client containing the network configuration, mountpoint details and information about the client itself. A new client configuration (recovery point) is generated on subsequent backups if the client's hardware has changed, or changes have been made to the network, storage or mountpoint configuration.

Use the client configuration stored on the CommServe to create a recovery response file needed to perform a non-interactive recovery.

1. Connect a USB drive to a Linux computer and use the following command to format the USB drive:

mkfs.vfat -I /dev/<drive_name>

For example: mkfs.vfat -I /dev/sdb

Do not partition the disk. Use the drive as a full disk.
 
2.
  • From the CommCell Console, navigate to <Client>
  • Right-click the <Client> and click All Tasks | 1-Touch Recovery Point
3.
  • Select the most recent client configuration to create a recovery response file.
  • Click Export Config.
4.
  • Enter the credentials used to login to CommCell Console.
  • Click OK.
5. Save the recovery response file as onetouchresponse.xml.
6. Connect the formatted USB drive to the computer where recovery response file is stored.  
7. Copy the recovery response file to the formatted drive.  
8. Connect the USB drive to the client.  
9. Boot the client using the ISO image.  
10. Type Default and press Enter to start the default recovery.
11. Select OK and press Enter to start the system state and file system restore.

The system state and the file system data backed up during the most recent backup will be restored.

13. Press Enter.
14. Remove the 1-Touch Linux Live CD and reboot the system.  

Interactive Restore

Perform the interactive restore when you don't want to use the recovery response file.

1. Keep the Client Information Checklist ready.  
2. Boot the client using the ISO image.  
3. Type Default and press Enter to start the default recovery.
4. Enter the short name or the fully qualified client hostname specified in the client information checklist.
  • Select the Use temp client during recovery option if you want to create a new client temporarily during the restore process. This option is not required for regular 1-Touch recovery. For more information, refer to Use Temporary Client during Recovery.
  • If a temporary client is being used during recovery, the New Client Host Name must be unique on the CommServe. Otherwise, any other existing client with the same host name will be renamed and the associated backed up data will be lost permanently.

Select Next and press Enter.

5. Enter the IP address, network and name server details of the network specified in the client information checklist.

Select Next and press Enter.

6. Enter the details of the CommServe and MediaAgent specified in the client information checklist.

Non-Interactive Restore

A recovery point is a point-in-time configuration of the client containing the network configuration, mountpoint details and information about the client itself. A new client configuration (recovery point) is generated on subsequent backups if the client's hardware has changed, or changes have been made to the network, storage or mountpoint configuration.

Use the client configuration stored on the CommServe to create a recovery response file needed to perform a non-interactive recovery.

Change the Client Configuration during interactive restore

During interactive restore, follow the steps given below to change the client configuration:

1. Boot the client using the ISO image.  
2. Type Default and press Enter to start the default recovery.
3. Enter the short name or the fully qualified client hostname.

You cannot change the client name during the restore.

  • Select the Use temp client during recovery option if you want to create a new client temporarily during the restore process.. For more information, refer to Use Temporary Client during Recovery.

Select Next and press Enter.

5. Enter the details of the CommServe and MediaAgent that are used to backup the client.

Select Next and press Enter.

6. Continue the Similar or Dissimilar System Restore  

Use Temporary Client during Recovery

You can change the client name and the host name temporarily during the restore process. This will be useful if the source computer and the computer being recovered are different and you do not want to turn off the source client until the restore completes successfully. You can also use this option when the source machine and the machine being recovered are same, to prevent corruption of the source client if the recovery process fails for any reason.

  1. Boot the computer where you want to recover the client using the ISO image.
  2. Type Default and press Enter to start the default recovery.
  3. Enter the short name of the client in the Client Name field.
  4. Enter the fully qualified hostname of the client in the Client HostName field.
  5. Select the Use temp client during recovery option.
  6. Enter the client name, which you want to use temporarily during the restore procedure in the New Client Name field.
  7. Enter fully qualified hostname of the client, which you want to use temporarily during the restore procedure in the New Client HostName field.

    If a temporary client is being used during recovery, the New Client Host Name must be unique on the CommServe. Otherwise, any other existing client with the same host name will be renamed and the associated backed up data will be lost permanently.

  8. Complete the Similar or Dissimilar System Restore procedure.

During the restore, the Linux File System iDataAgent will be installed in the restore only mode with the new client name and host name. The CommServe and MediaAgent should be able to connect to the computer being recovered with the new host name. After the restore completes successfully, the temporary client will be deleted. The original client name and hostname and network settings, which were backed up will be restored.

You must turn off the source client before rebooting the restored client.

Use a NFS Location for Non-Interactive Restore

Instead of using the USB drive, use a NFS location to access the recovery response file during the similar or dissimilar system restore.  Follow the steps give below to perform the non-interactive restore when the recovery response file is stored in a NFS location:

1. Boot the client using the ISO image.  
1. Type Default and press Enter to start the default recovery.
2. Select Select Location to specify the NFS location of the response file.
3.
  • Select Use NFS Path.
  • Enter the NFS Server Name or IP address.
  • Enter the response file path on the NFS server.
4.
  • Enter the IP Address of the client.
  • Enter Net Mask of the client.
  • Enter the Gateway of the client.
  • Enter the DNS Suffix for the client.
  • Select Next and press Enter.

The system state and the file system data backed up during the most recent backup is restored.

5. Follow the steps described in the Similar System Restore or Dissimilar System Restore depending upon the hard disk configuration of the client.
