Windows 7 Backup Destination Types

Here are some tips to help manage your backups:

You can select the following types of backup destinations in Windows 7:

Additional internal hard drives – As hard drives are getting larger in size and
cheaper to buy, this option has become a good candidate for backup destination. It
is an inexpensive and secure solution while provides fast I/O. It is important to
note that, if your computer has two internal drives and you have configured dual-
boot with an operating system on each drive, then you cannot use either of the hard
drives as a backup destination.
External hard drives – Although external hard drives are more expensive than
internal ones, they offer other benefits such as portability and better disaster
recovery functionality. These drives can be removed and stored in a secure location.
You need to factor in speed as these devices are in general slower than internal
drives and you need to make sure that they are always connected if performing
scheduled backup jobs. Also, some devices are powered by an external power source
which adds an extra point of failure! It is important to note that many external
drives are formatted using FAT due to compatibility issues. System Image backup
cannot be saved on FAT systems but need to be converted to NTFS.

DVD-ROMs – Optical disks are inexpensive and can be archived in a secure location.
You can back up to both CD-ROMs and DVD-ROMs but in practise a typical backup
would need a large number of DVDs or CDs hence, making this option impractical.
Note, that DVDs can become corrupted over time (years) and you cannot save
scheduled System Image backups on DVDs.

USB flash drives – Flash drive memory is less expensive than hard drives and the
available sizes are quite sufficient for personal data backups. Remember, that you
cannot save System Image backups to flash memory but they are good candidates
for offsite storage and portability. They are easy to lose or displace, so consider
encrypting the data!

Network locations – This option is only available on computers running Windows 7
Professional, Windows 7 Ultimate and Windows 7 Enterprise. You need to provide
credentials so that Windows Backup can access the network and that the remote
has enough storage space to contain the backup. Also, the network bandwidth or
speed is an important factor you need to consider before going for this option.

VHDs – In Windows 7 you can specify a VHD (Virtual Hard Drive) as a backup
location where you can carry out a System Image backup of an entire volume to a
VHD disk image file. These disk image files can be made bootable on Windows 7
Ultimate and Enterprise editions. Note, that the VHD file should not be on the
physical disk that you are backup up!

This unit describes the performance outcomes, skills and knowledge required to
operate and support system software.

Problem-Solving Techniques

After you've got a well-documented network, all you have to do is sit back and wait
for problems to occur. Spurious as that may seem, it's true. Sometime, some day,
when you least expect it, something out of the blue will knock a server offline,
disable a printer, and so on. If you have good documentation, you can tackle the
problem and do so from a structured point of view.
The troubleshooting method known as the problem resolution cycle builds on
accurate documentation for the network and uses a simple question/answer
technique to determine what has changed to bring about the problem.

The Problem Resolution Cycle
The problem resolution cycle is a method designed to meet two needs: to solve the
immediate problem that prevents the network (or a component of the network)
from working, and to provide insights as to the cause of the problem so that it can
be avoided or quickly solved in the future. The elements of a structured problem
resolution cycle approach are as listed here:

Accurate and complete descriptions of the symptoms. Determine whether a
problem really exists, or whether the user is using the computer or application

Understanding how the network functions from a logical and physical point of view.

Solving the problem instead of creating a makeshift fix.

Providing a follow-up mechanism for recording and distributing solutions to others
who may have a need to know, such as staff at a help desk or a departmental

Development of a solution-tracking system to keep you from having to solve the
same problem over and over again.

In most cases, the more data you can collect about a problem, the easier the
problem will be to solve. When selecting employees who will serve as help-desk
personnel, for example, try to get someone with both good verbal and good listening
skills, not just someone with technical know-how. Although the initial problem
report might be something like "I can't print this document," a good help-desk
technician can usually walk the user through a series of questions to determine
whether other symptoms are present. In the example just given, it would be
prudent to ask whether the user can print other documents, or whether the
problem is with just the one document. What about different types of documents?

    website is a valuable tool: www.myfuture.edu.au
   Make a list of potential jobs, using such resources as the Job Guide:
   Ensure that you can safely perform all or most of the tasks involved in any
    possible job. You can do this by talking to people in the industry to get an idea
    of what is actually required on the job.
   When you have decided on a suitable job or goal, ensure that you have a current
    resume which clearly identifies your skills
   Research available jobs using a range of methods, for example websites such as
    www.jobsearch.gov.au , print media and personal networking
