A Support of GVFS Caching
Holý, Ondřej ; Zelený, Jan (referee) ; Smrčka, Aleš (advisor)
The master's thesis deals with a support of caching in GVfs (Gnome Virtual filesystem). Basics of caches, cache invalidation, and cache replacement algorithms are described. Description of GIO filesystem abstraction and communication of modules within GVfs is provided next. The disadvantages of individual GVfs modules and, if present, their internal caches are discussed. The thesis proposes three types of cache. The first type of cache is for storing file metadata, the second one for directory listings, and the latter for file content. These caches have been implemented in a prototype and verified with respect to the functionality and performance. The main benefits of the proposed solution are faster work with virtual filesystems and provided missing functionality of lower-level virtual filesystem to GIO abstraction (namely, for instance seek operation).

Porting of RedirFS on Other OS
Czerner, Lukáš ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes preparation for porting as well aw porting itself of RedirFS Linux kernel module to FreeBSD. Basic differences between Linux and FreeBSD kernels are described as well as differences in implementation of the Virtual Filesystem, crucial part for RedirFS. Further there are described possibilities and different approaches to implementation RedirFS functionality to FreeBSD. Then, the possibilities are evaluated and ideal approach is proposed. Next chapters introduces required functionality of the new module as well as its solutions. Then the implementation details are described so the reader can very well understand how the new module works and how the required functionality is implemented into the module.

iOS Forensic analysis for iPad, iPhone, iPod
PLACHOTŇUK, Artem
Thesis "iOS Forensic Analysis iPad, iPhone, iPod" deals with the forensic analysis of mobile devices running iOS. This paper will describe a specific OS iOS devices with this operating system. Next will be described the capabilities and limitations which have these devices in relation to forensic analysis. These findings are then illustrated on a physical device and on the basis of best practices will be designed for forensic analysis of these devices and the findings will be evaluated.

High-availability solutions for network filesystems in Linux
Kravec, Martin ; Pavlíček, Luboš (advisor) ; Vadinský, Ondřej (referee)
The goal of this paper is to inform readers about high availability problematics and provide basic overview of free technologies you can use to achieve high availability. I focus mainly on solution of problems caused by hardware failures. Document can by used to gain basic knowledge needed for configuration of your own solution. In practical part I will try to realize high available cluster using free technologies and compare performance of different filesystems on this platform. Document will provide instructions for choosing and testing appropriate filesystem for specific configuration that can be used in production environment.
