Sažetak

Current practice of backing up data is based on using backup tapes and remote locations for
storing data. Nowadays, with the advent of cloud computing a new concept of database
backup emerges. The paper presents the possibility of making backup copies of data in the
cloud. We are mainly focused on performance and economic issues of making backups in the
cloud in comparison to traditional backups. We tested the performance and overall costs of
making backup copies of data in Oracle database using Amazon S3 and EC2 cloud services.
The costs estimation was performed on the basis of the prices published on Amazon S3 and
Amazon EC2 sites.
