Backup system


No matter how reliable the hardware, how well written the software, how well configured, or how physically secure a computer system is eventually it will fail - usually in an unexpected manner. As it is impossible to completely protect against this kind of failure all we can do to mitigate the losses associated with such a scenario is to protect valuable data stored on the system from loss.

This documentation aims to be a thorough discussion of backup systems and strategies including the use of a variety of technologies to backup files and databases in the most common usage scenarios. We shall also discuss the use of the Internet and the "Cloud" as storage mediums for off-site backups as well as covering how to install and configure some common production software to operate in a high-availability environment.
