Descriptions Unix Backup and Recovery book
As the somewhat bitter joke has it, backups are too boring and expensive to bother about: only restores are important. In practice, backups are a business necessity like liability insurance. And, like insurance, it's important to get it right.
This is where Curtis Preston's UNIX Backup and Recovery dazzles. His enthusiasm for the subject shines from the pages. His primary concerns are heavy-duty business UNIX systems and the corporate databases they run, but he starts you off easy with the basics of tar, dump, cpio and other UNIX system utilities. You get discussions of disaster scenarios, planning, media types, native and commercial utilities and endless gotchas--those situations where life irritatingly fails to follow the theoretical models.
The strength of the book, though, is the sheer quantity of practical advice from someone who has clearly been there. This includes a supporting Web site with scripts, discussion, a mailing list and real life experiences. This experience extends to new breeds of file system, the relational databases that rely on them and strategies for securing them. The section describing the logical and physical structures of databases such as Informix and Oracle are worth the price of the book on their own. UNIX Backup and Recovery deserves to be a standard work for anyone whose job depends on data integrity. --Steve Patient, Second Grade Reading Books .
