TODO: Add information about the base operating environment (currently Debian woody and sarge) and about dealing with different versions of key service packages. Add information about the use of README files in backups.
Recovering a service from backup
If the machine running a service is lost, or the service has to be built on another host, these are the steps to getting the service up and running.
- Locate the tar file which is the latest dump of the service. If you do not have a copy, contact the backup administrator.
- Create the accounts and groups needed by your service
- cd to the root directory (because all dump tar files should have been made with respect to / (see above)).
- Check what the backup tar file contains by running tar with the -t flag.
- Stop any services that might be affected by the replacing of files in the backup.
- Un-tar the backup. This should put all the key files back in the right places if the backup strategy has been correctly implemented.
- Restart services as required.
- Test the new system!
