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.
