KINDELMANN, Ladislav
The aim of this dissertation is to analyze the way data backup of remote sites deduplication technology system used by EMC Avamar. This is a special type of data compression used not only when saving to disk arrays, but also in a virtual environment. Deduplication ensures saving storage space and reliability of data recovery. EMC Avamar system is one of the best-engineered and most extensive systems of which the above technology is used. The dissertation is divided into two parts - theoretical and practical. In the theoretical part student briefly summarize the available backup technologies and describes the remote backup methods, including examples using available software and hardware requirements. Then it specifies details of EMC Avamar and its implementation, HW requirements and functioning of the entire system. Student will analyzes the data deduplication technology, which the system uses, description of data transferring and the possible advantages and disadvantages compared to other systems. In the practical part it creates own proposal for implementation of data backup using the above mentioned system in a business environment between the two branches of the company. The aim will be to show the real technology features, advantages and shortcomings. The conclusion of the dissertation the student all accompanied overview of the use of backup systems in today's global market.
