An Introduction to Tape Backup Computers Articles | March 12 Wholesale Billy Price Jersey , 2005

If you run a small business, chances are you're saving important files to a server. But what happens when disaster strikes? How are you ensuring that your files won't be lost? Many people fail to realize that the loss of files could cripple their business. You can insure your office and equipment, but you can't insure files. You can't repair or buy back lost files. Ipso facto, they are lost!



This brings us to the concept of disaster recovery. What is disaster recovery? If you're thinking that disaster recovery is about frantically trying to get back data that's already been lost, then you're already behind the 8-ball! Disaster recovery is about safeguarding your organization's data so that it can be safely restored in event of a crippling disaster. And having an industry-standard file backup strategy is undoubtedly the most important part of disaster recovery.


What you have to do is ensure that all files on the server are backed up to another storage medium - tape Wholesale Michael Jordan Jersey , removable hard disk, NAS device, and so on. Most businesses choose to use tape. Let's look at how you can set up a tape backup strategy for your own business.


1. Tape - the perfect backup medium


Isn't tape an anachronism in the age of optical disks, removable hard drives and a plethora of whiz-bang, random-access storage media? Tape is indeed a dinosaur in relative terms Wholesale Renell Wren Jersey , but it's ideal for backup. Tape is slow, but can store a lot of data... one mid-range tape should be enough to backup your entire server. Plus, tape is extremely cheap - mid-range tapes cost around $20 each.


2. When should you backup?


Typically, tape backup is performed at the end of each day. Just put in the tape and let the backup process run overnight. If your server ever suffers a catastrophic disaster, you have at least saved all your files from the previous day.


3. Tape Rotation


The ideal tape backup solution would involve using a new tape for each backup. This means purchasing a new tape for every day of your business's operations. This is hardly cost-effective for your business. Tape is cheap Wholesale Ryan Finley Jersey , but not that cheap!


This is why we speak of tape rotation. Tape rotation means to reuse tapes from previous backups. The simplest tape rotation scheme is to have one tape for each day of the working week. Tapes are labeled Monday, Tuesday, Wednesday, Thursday and Friday.


You can restore data from any one of the tapes in your library, or in this case Wholesale Germaine Pratt Jersey , any day in the past the week. This strategy requires only five tapes, but only provides one week's data backup history.


4. Grandfather-Father-Son - A Case Study


The grandfather-father-son schedule is the most widely used method, and involves backing up data in the following way:


* daily - on the "son tapes"
* weekly - on the "father tapes"
* monthly ? on the "grandfather tapes"
