Tax Advising
Psohlavec, Karel ; Hochman, Karel (referee) ; Polák, Michal (advisor)
Bachelor thesis examines the circulation of documents in the selected firm and its archiving in conjunction with legislative constraints and possibilities. It deals with the issue of effectiveness of this system. It compares the document obligations of three parts of the company and their mutual conection and proposes more efective ways of dealing with this system using the internal guidelines.

Design of optimal utilization of company's data capacities
Odehnal, Tomáš ; Hrbáček, Miroslav (referee) ; Ondrák, Viktor (advisor)
The diploma thesis deals with the problem of storage capacities of server discs in the allowance organization of Brno City Museum. The organization has long-lasting troubles with insufficient capacity of these discs. The aim of this thesis is to analyse the current state and to propose a suitable solution on the basis of the results of this analysis. Further, the suggested measures should be applied as well.

Possibilities of archiving NC programs in small versus large companies
Mikulec, Jan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with archiving of NC programmes in engineering companies. The theoretical part describes how the machine tools and their archiving tools are developed. Then the NC programme is characterised together with its structure and the importance of individual characters, followed by characterisation of currently used archiving tools and description of NC programmes labelling that simplifies the archiving. The last part is dedicated to practical examples of the NC programmes archiving and their comparison. The thesis is supplemented with examples of archiving programmes used in chosen companies.

The Optimalization of a Data Backup System
Klvaňová, Anna ; Dostál, Ivo (referee) ; Kříž, Jiří (advisor)
The topic of the Bachelor´s Thesis is The Optimization of a Data Bacup System. It analyzes the existing problems of the company either directly in the field data backup, or in areas which are closely related to this topic as well. The work includes design of the optimization backup system, so that it is beneficial to the company and also to the employees. These proposals are grounded in theoretical backgrounds, which are also included in this work.

Cloud-Based Data Access Control
Chovanec, Erik ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This thesis is dealing with problematic of cloud storage. The goal of this thesis is the implementation of cloud storage, that will be able to provide the required functionality. These functionalities are access control of multiple users, group rights, long-term file archiving, secure data transmission to cloud storage, protection of data integrity and confidentiality during transmission and storage. For achieving this goal, there is an evaluation of suitability using public cloud providers. Based on this evaluation, there was a conclusion, that these services are not suitable for storing highly sensitive data. Next is an evaluation of advantages associated with using software that is licensed under a free or open-source software license. Even though there are high start-up costs on infrastructure and there is a necessity to make a huge effort to run custom infrastructure with cloud storage, it is a much better option. Especially if it will be used for storing sensitive data. The following chapter describes an extensive analysis of existing open-source and free-software solutions. In the final part of this chapter, the application Nextcloud has been selected since it provides the most of required functionalities. The thesis also contains an installation of Nextcloud and shows its main functions. There are basic load tests, which are telling us about the efficiency of successfully dealing with parallel requests. In the last section of this thesis, we are dealing with the implementation of missing functionality in Nextcloud. This functionality is necessary to achieve our goal, which is long term archiving of files. This term means functionality that will enable the possibility to archive files with evidence about preservation integrity and confidentiality of archived files during a long period of their existence. This part of the thesis contains a theoretical design that aims to accomplish this goal. Description of the implementation follows after theoretical design. This functionality is implemented in form of a dedicated system. Archiving of files is triggered by a modified application, used in the Nextcloud server. This process will create a copy of the file to be archived on a separate hard drive. It will obtain evidence about integrity when storing the file and it will strengthen this evidence by obtaining a new one in regular periods. This happens on yearly basis. The quality of cryptographic protocols can degrade after a long period. This concept is trying to prevent this phenomenon.
