Backup Tips


Creating original documents is dangerous work.  Hours of irreplaceable work can be destroyed in a flash due to computer hardware failure, virus infection, disk failure, or user error.  “Backup” is the most practical means of protection.

“Backup” means keeping one or more extra copies of your document, preferably in separate places.  Imagine the worst:  what would you do if your computer crashed and you lost everything on it right now?  What if the building burns to the ground?  How much work would be lost?  What would you have to do to replace it?

Data/Software Backup Tips:

Hardware Backup Tips:

An individual usually doesn't need hardware backup.  If your computer is destroyed, buy another one and restore your data, which should be backed up as above.  Businesses, however, may need to get back in operation much faster than if they had to buy new hardware after a disaster, especially if they use hardware other than what you can buy at the local computer store.  In those cases, the business may wish to have backup hardware that could be used quickly if the main hardware fails or is destroyed.  Protection against disaster would of course mean storing the backup hardware separate from the normal hardware.  Some firms even go so far as to keep a complete backup system in operation with the ability to switch to it instantly if there is a problem.

Network Backup Tips:

Again, an individual usually doesn't need network backup.  If your Internet connection goes down, just wait till it comes back up, or call your Internet provider's technical support.  Businesses, however, may rely heavily on the network, and they may lose money rapidly if it is down.  In such cases, the business may wish to have an alternate connection to the Internet.  Caution:  make sure the alternate connection uses separate physical cable.  Many Internet providers share telephone and data lines, so more than one provider may be affected if for example a fiber optic line is cut.
