The book begins with detailed explanations of native backup utilities available to the Unix administrator, and ends with practical advice on choosing a commercial backup utility.
Every user dreads the inevitable computer crash or system failure.
For the individual user, it means lost time, inconvenience, and occasionally some additional expense. For the systems administrator, the consequences range from downtime to data loss and unrecoverable revenue. The alternative to these scenarios relies on consistent backups and thorough recovery procedures, allowing for every situation. This contingency policy is not impossible, but it does require a lot of thought, planning, and testing. In UNIX Backup and Recovery, W. Curtis Preston examines the need for complete backup strategies and demonstrates how to implement them.
