Tips and Tricks using Relax-and-Recover

Recovering a system should not be a struggle against time with poor tools weighing against you. Relax-and-Recover emphasizes on a relaxing recovery, and for this it follows three distinct rules:

  1. Do what is generally expected, if possible

  2. In doubt, ask the operator or allow intervention

  3. Provide an environment that is as convenient as possible

This results in the following useful tips and tricks:

  1. Relax-and-Recover can add its own GRUB menu entry to your local system’s GRUB, which is convenient to restore a system without the need for an additional boot media. This only works if your system can (still) boot from the local disk and the disaster didn’t destroy that disk.

  2. Relax-and-Recover automatically detects and enables serial console support. This is extremely useful if the only way to access the console during disaster is a Java-based console riddled with keyboard bugs and slow screen refreshes.

  3. Relax-and-Recover conveniently ships with a set of useful commands in its shell history. This makes it possible to quickly look for a command to help troubleshoot, or modify an important file during recovery.

  4. If you have keyboard problems using a HP iLO 2 Remote Console, type the following command loadkeys -d (or simply use the up arrow key to get this command from your shell history).

  5. If the original system was configured to log on remotely through the use of SSH keys, Relax-and-Recover preserved those keys on the rescue environment and you can access the rescue environment from the network as you were used to before.

  6. During recovery at any stage you can re-run Relax-and-Recover, modify the layout file for recreating the structure and intervene when restoring the backup.
