Our WinPE 2.1 recovery environment is 32-based, thus you need to use 32-bit

drivers for injection.

Basic Concepts

This chapter explains terms and ideas that show how the program works. To understand these helps

to obtain a general notion of the operation performance and makes it easier for the user to operate

the program.

System and Data Protection

The data protection issue is a growing cause of worrying for more and more people today. Indeed, it

is hardly to find a person who will be particularly happy when all precious information on the hard

disk is irreversible lost as a result of its malfunction. So how this tragedy can be prevented?

File Backup versus Sector Backup

Since the advent of the computer age people were in the search of ways to guarantee data safety.

As a result we’ve got now two principal approaches: the file-based backup and the sector-based

backup. The main difference between the two lies in the way data is treated.

A sector-based backup operates with an image (or a snapshot) of the whole disk system or its

separate partitions. It not only includes the contents of all user-made files, but additionally contains

the exact structure of directories, information about file allocation, file attributes and other related

data. Thus it enables to successfully process system or encrypted partitions of any file system type, no

matter what kind of information they contain.

In contrast, a file-based backup takes into account a file system structure and only functions on a file

or folder level. So it is very efficient when archiving separate files or folders, but in no way will help you

back up a system partition.

You should understand pretty well that each of the two approaches is only good when properly

chosen. In the comparison table below you can see when this or that approach will suit you at most.

Sector-Based Backup File-Based Backup

Merits

It does not dependent on a particular file

system. Thus it can successfully process

system or encrypted partitions of any file

system type, no matter what kind of

information they contain.

Functioning on a file/folder level, it is ideal

for archiving separate files or folders.

It can create an exact image of a

partition, including its service data. Thus it

is ideal for a backup/restore of a system

partition or a fast deployment to a bunch

of identical computers.

It enables to automatically build up

contents of the future backup image by

using an advanced system of filters.

It allows archiving data of the same

volume with different backup policies.
