Backup & Recovery

What Hacker News says

   While it's a bit dated, this book, Backup & Recovery: Inexpensive Backup Solutions for Open Systems (http://www.amazon.com/Backup-Recovery-Inexpensive-Solutions-...) is highly recommended. And higher level programs like BackupPC and Bacula are still excellent solutions.

   It's comprehensive, covers off-line bare metal backups (which aren't exactly changing any time soon), points you at tools like rdiff-backup which you can use to get reasonably close to continuous data protection (I do it every hour), etc. etc. Along with a few good and short war stories. And preps you for the big times, if you're interested.

   W. Curtis Preston, author of the O'Reilly book "Backup and Recovery" has said:

   > Backups are useless. Restores are priceless.

   I also like:

   > The state of a backup is unknown and unknowable, until such time as it has been tested with a restore.

   In the late 1990s, W. Curtis Preston wrote a book called “Unix Backup and Recovery”. A later version was just named “Backup and Recovery”. Both were published by O’Reilly.

   He was saying similar things at that time (e.g., “Backups are worthless, Restores are priceless”), and I’m certain he wasn’t the first.

   But you’d have to ask him who was saying things like that before he did.

   Disclaimer: Curtis was a co-worker of mine at the time, and I was a technical reviewer of the book in question.
