Book Review: Tarsnap Mastery Online Backup For the Truly Paranoid

Book Review: Tarsnap Mastery Online Backup For the Truly Paranoid
Tarsnap Mastery: Online Backups for the Truly Paranoid (IT Mastery) It’s always a good idea to keep backups of all of your data in multiple places. Every Linux or Unix sysadmin must master the art of backups if you want to keep your data forever. Most sysadmin recommend and follows the 3-2-1 rule:

  1. At least three copies of data.
  2. In two different formats.
  3. With one of those copies off-site.

Tarsnap is one of such off-site backup sites. It’s a secure online backup system for UNIX-like system. This service encrypts and stores data in Amazon S3. To use Tarsnap perfectly and feel secure about your backups, you need the “Tarsnap Mastery” book by Michael W. Lucas. It is no secret that I’m a big fan of his book series. Let’s see what the book is all about.
