BACK-UPS

Back-up is a crucial process that everyone should do in order to have a fail safe for when an inevitable happens. We have different types of back-ups.

1.      Full back-up

It assumes each time you execute a task the entire set of data is copied to the chosen place. This type of back-up takes the most disk space, time and PC resources and often does a lot of senseless work.

2.      Incremental data back-up

It processes only file that appeared or changed since the previous back-up. They may be of two reasons. When files are written on the same folder where the full back-up is or when files are put into a separate folder.

3.      Differential back-up

Its very much like incremental back-up with the only difference that it doesn’t upgrade the index file with each task execution and therefore each task execution process or modification since the last full back-up.

4.      Mirror back-up

It’s identical to full back-up with the exception that the files are not compressed in zip files and they cannot be protected with a password. This type of back-up is most frequently converted to create an extra source of the data.Note: The first time when it runs mirror back-up will back-up everything without archiving only new or modified remain.

Summary table of the four types of back-ups:

Back-up type	Data backed-up	Back-up time	Restore time	Storage space
Full back-up	All data	Slowest	Fast	High
Incremental back-up	Only new/modified files/folders	Fast	Moderate	Lowest(Best)
Differential back-up	All data since last full back-up	Moderate	Fast	Moderate
Mirror back-up	Only new/modified file/folders	Fastest	Fastest	Highest

PC Diagnostic testing and maintenance

No matter how well build your PC is and how well written its software, something is eventually going to go wrong and you might not always have support available to resolve the problem. Diagnostic software can be very important to you anytime your computer malfunctions or you are in the process of upgrading a system component or building an entire system from scratch.

Troubleshooting tips and technologies

Troubleshooting PC hardware problems can be seen doubting to be initiated but in realistic its much simpler than it seems. Most problems can be diagnosed or corrected using few special tools. Troubleshooting a PC can be accomplished by anybody who can apply simple reasoning and logical thinking.

The bottom-line with troubleshooting PC problems is that a solution exists for every problem and through simple practices combined with dedicated reasoning that solution can easily be found. In any PC we have software and hardware problems. Hardware problems comes first because if any component of a PC is not running as supposed to you get error and beeps that alert you of any hardware issues. BIOS (Basic Input Output System) control and configure each and every hardware component in a PC. With hardware problems the best thing to do is to replace than to repair.
