Protecting data with a Perl-based rescue CD
PERL RESCUE
Armed with just a rescue CD and a Perl script, you can back up a client’s hard disk across the wire.
What do you do when a hard disk crashes? Just buy a new hard disk and restore your most recent backup, of course. But what happens if you had a configuration with multiple partitions on the disk? How much space was assigned to each partition, and what filesystems did you have on the disk? Disaster recovery is a fairly easy process if the backup includes the complete partitions and you can restore the backup in a single operation.
