In the ITESCAM, there is a policy of restoration for the
computer labs where the stable initial configuration of
all the needed programs is returned.
Currently, there are authors like Pressman that esta-
blish criteria for measure of software quality. In this
document we present the compilation and classifica-
tion of this information divided in three criteria: ease to LSP does not specify a criterion, but it gives us a me-
install, ease to use, performance and maintainability,
integrated through LSP methodology for, in a quanti-
tative manner, compare two or more software’s and
determine the better, using the established indicators;
in addition, we show the results of use it with three
restoring and cloning tools for the equipment of ITES-
CAM computer center.
State of the art
The dedicated area for its required maintenance to
protect needed programs of providing services either
for poor performance, virus or organization policies, in
order to maintain service levels [1]
Taking the advantages of the computer lab, the mana-
gers can use features of different programs to make a
massive installation of the full content of hard disks, no
matter if you have installed two operating systems (in
some disks) or if you have installed some programs.
If a manager does not implement any of the programs
that we will evaluate, to perform this work can be te-
dious and inefficient and it would take too long to fini-
sh the activity, because it would imply that the resto-
ration of operating systems (one or more), drivers and
applications installation that are used is going to be
made computer by computer.
In the current market there are tools of software (co-
pyright or copyleft) that offer disaster restoration, disk
cloning and backup that are ideal to apply on com-
puter labs or in connected computers by net for an
efficient maintenance in the computers.
We name disk clone or Disk Image, as an exact copy
of computer hard disk drive. The copy includes all
the partition information, boot sectors, the file alloca-
tion table, operating system installation and software
application. It saves the entire data from the disk, in-
cluding the file structure and all the files and folders
from the disk, in a single file [2]
Evaluate a system means establishing criteria based
on properties that are expected to have, it can be
made using oriented methods for economic effects,
trying to express criteria in terms of financial indica-
tors, from the perspective of quality with the classic
works of [3] and [4], through metrical standards of sof-
tware quality established in [5] and [6]., nevertheless
metrics quality standards are standardized, evaluation
methods that operate over these are different as can
54
be shown in [7], and usually are always focused on
aspects of software design and development. One
of the quantitative methods is Logical Score Preferen-
ce (LSP). It is used to evaluate, compare, and select
software and hardware, and is a generalization and
extension of several techniques of qualify [8] and [9] .
thod to get a list to evaluate quantitatively criteria for
comparing as is showed in [10].
The chosen tools are: Acronis, Clonezilla SE and Sy-
mantec Ghost Solution Suite that permit creating and
cloning an image.
MATERIALS AND METHODS
Methodology
An experiment was made using Installation Labs of the
institute with thirty-five computers for the massive de-
ployment of a disk image from a hard disk of 500Gb
containing 80 GB of information and with two opera-
ting systems: Windows 7© and Linux Ubuntu 14.04.
At the beginning of the test we followed next steps:
i. Review Connectivity
ii. Operating System Installation as a server
iii. Preparation of a client computer to install required
operating systems and applications in the computer
lab.
iv. Installation of cloning software on the server
v. Saving the disk image on the client from server.
vi. Cloning target computers of the computer lab.
Software Description
The characteristics of the three tools to be used to
accomplish the target are presented below:
Clonezilla SE. It is a free software used for restoration
management of hard disk to different clients, it is a
tool that permits to start the operating system in the
net machines, without having an operating system ins-
tallation in the locally, with Clonezilla (included) we can
clone several computers simultaneously. It is a pro-
gram that works over Linux distributions and permits
to clone the hard disk. It is important to mention that is
an open software, available for all users.
Symantec Ghost Solution Suite. It is a commercial sof-
tware that is used for the creation of disk images of
systems; and it is compatible with Windows, although
it can install in other operating systems using another
tools.
Acronis It provides security copies and restoration
solutions after disasters and let us access to security
data through a security software giving us access to
security data in physical servers, virtual servers, and
the cloud. It includes a feature called Universal Res-
tore that permits to restore security copies simulta-
neously on any computer, independently of the pla-
tform.
