The importance of computer backups

The importance of computer backups Bill Gates, founder of Microsoft once compared the computer industry with the automobile industry stating "If General Motors had kept up with technology like the computer industry has, we would all be driving $25.00 cars that got 1,000 miles to the gallon." General Motors responded by saying "That's true but who would want to drive a car that crashed twice a day?"

The importance of computer backups It's not a matter of IF your computer is going to crash but a matter of WHEN. WHEN your computer crashes you could lose all of your important documents, pictures, email, and other files that will be gone forever IF you don't have a reliable backup.

The importance of computer backups If a business were to lose all of its customer records, financial data, or programs & data critical to running the company it could possibly shut the business down temporarily or even permanently. Even losing one critical file could cause major problems. As a network administrator it's your job to make sure this NEVER happens.

History of Backups Once upon a time a FLOPPY DISK was an acceptable method for backing up or transferring data. Today there is a wide range of choices for backing up and transferring data.

Types of Backups Portable storage devices such as USB Jump Drives are great for transferring data. But for dedicated routine backups there are better choices. External Hard Drive Network Attached Storage Cloud Backups

External Hard Drive An external hard drive equal or greater in size to your computers internal hard drive is an easy way to backup everything. Most modern operating systems have a built in backup program or you can use a 3rd party backup solution such as Norton Ghost for Windows or Carbon Copy Cloner for Mac. PROS: Inexpensive, Easy to Setup. CONS: May not survive a disaster such as a house fire or if your computer and external drive are stolen you are out of luck.

Network Attached Storage A Network Attached Storage (NAS) system is a backup server that acts as a local drive for computers on a local area network. A NAS usually has redundant hard drives (RAID) and synchronization to another NAS at another location for further redundancy. PROS: Extremely Reliable, Fast and Secure. CONS: Expensive and requires technical expertise to setup and manage.

Cloud Backup A cloud backup is actually a service that you pay for to have your data backed up over the Internet to a remote location. Examples: Mozy, Carbonite, Backblaze PROS: Affordable Monthly Fee, No Equipment to buy. CONS: Depending on your Internet connection can be slow to backup and restore files.

Online Synchronization Similar to a cloud backup, online file synchronization services work like a Personal NAS that allows you to open and edit files from multiple locations and the changes stay in sync. For instance you could work on a file on your home computer and any changes you made will be there when you get to work or school. Example: DropBox.com
