Bare Metal Recovery, Revisited

Charles describes the additions he made to the scripts for his backup and recovery suite.
Using the Script

The script make.fdisk should be run as a normal part of preparing for backing up for bare metal recovery. Run it before you run save.metadata so that the output files are saved to the ZIP drive. Better yet, have save.metadata call it, once for each hard drive.

When you are restoring, run for each hard drive you have. Again, this can be automated by including it in restore.metadata.

There are other things you can do with this script. Suppose you want to add a new partition. Use the bare metal backup process to save a hard drive, then edit the dev.x command file to change the partition definitions and restore using the edited file. I successfully added a 30MB Mess-DOS partition to my test computer with this technique.


Some improvements that you can tackle if you like include having make.fdisk process several hard drives, all indicated on the command line; adding error checking for the argument(s) to make.fdisk, having it produce one script that builds all the hard drives, extending the FAT filesystem support (for one thing, right now the code ignores FAT32); and extending the code to support other filesystems.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
