Low-level data reading from computer data storages
Šalko, Jaroslav ; Ležák, Petr (referee) ; Burda, Karel (advisor)
The following work is topically focusing on data restore of selected memory devices. It could be divided into two theoretical parts and one practical. The first part consist explanation of these memory media’s structure, the mechanism of their storage and also how operating system approaches these data. This relates also to a file system, which is among with its most commonly used types described there as well. In the second theoretical part the study focuses on the storage damage problematics. Various types of damage are shown and I examine how we could approach them. The work concentrates on possibilities which owners of the damaged storage media have with an emphasis on specialized companies. Therefore the study contains brief information of four selected domestic companies which are offering data restore on the Czech market. The complete list of services, which these companies offer to their customers, is shown in the chart found by the end of chapter. The second option in order of solving media damage problems are freeware programmes. On the basis of an internet poll dealing with the topic „best programmes for data restore“, I have chosen three programmes to be examined. The examination consisted of uploading certain files on the media storage which was formated by high level method afterwards. Through these three programmes I tried to restore the lost data. The results are included in a chart found by the end of each sub-chapter. The practical part of my work deals with linux program for data restore DDrescue. My effort consists of developing and creating an user friendly interface with intuitive manipulation of this helpful tool. My goal is thus spreading this program into the public and providing them simple tool for efficient low-level data restore.

Data Backup and Data Storages
Lajčiak, Adrian ; Luňáček, Ing Petr (referee) ; Kříž, Jiří (advisor)
The topic of the Bachelors thesis is data backup and data storage. It analyzes the current data backup and recovery methods the company uses. Based on the faults and deficiencies a more efficient system for data backup is designed in order to avoid possible data loss. This new data backup solution is based on the theoretical framework included in the thesis.

Analysis of Private Information from FAT32
Križan, Lukáš ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The aim of this thesis was to create an application which can search for and recover specific files in the file system FAT32, and subsequently extract sensitive information from these files. The first part of this thesis describes the principles underlying FAT32, and focuses on how the analysed applications store information. The second part outlines the application and describes its implementation and simulations.

Data Backup and Data Storrages
Šmarda, Miroslav ; Švábenský, David (referee) ; Kříž, Jiří (advisor)
The bachelor´s thesis is concerned with backup and archiving of data in a real environment of an actual financial corporation. There is descripted a complete backup system as well as problems related to the system. There are mentioned suggestions for improvement of actual status to reach the maximum profit of it´s potential to allow to work faster, more transparent and more easily. The work contains as well the theoretical foundations, from which the improvement suggestion of actual status is patterned on.
