I’ve been accused of caring only about backups. It’s been said that I think the whole world revolves around a cartridge reel. I’ve said that someday the world’s going to crash, and I’m going to have the backup. The question is: how serious are you about protecting your data? To help you come to a decision on this matter, let’s talk about what happens if you don’t have good backups. That’s Not What I Meant! I was administering a QA group for a major software company. When the software did its setup, it created a directory in $HOME/foo so the software could install the user portion.
The cost of a reasonably priced disk array is now approximately the same price as a similarly sized tape library filled with media. When you consider some of the things you can do with disk, such as eliminating full backups and redundant files, disk becomes even less expensive. Reliability Unlike tapes, disks are closed systems that aren’t susceptible to outside contaminants. In addition, the actual media of a hard drive is, well, hard when compared to a piece of tape media. The result is that an individual disk drive is inherently more reliable than a tape drive.
17 long nights and weekends in computer rooms trying to recover data in a “reasonable” amount of time. Unfortunately, “reasonable” is defined by the end user who has no idea how difficult this job is. There are now solutions to almost every backup problem out there. If you run a small shop with just a few systems, all of which run the same operating system, there’s a solution for you. If you work in a huge shop with hundreds of boxes in the various flavors of Unix, Linux, Windows, and Mac OS, or just a few multiterabyte databases, there’s a solution for you.
