Summary: Long Live TSM
Review: IBM Tivoli Storage Manager is the best software suite on the market for enterprise disaster recovery needs by large businesses and organizations. It is simply the best backup software solution out there. The only two serious competitors in the marketplace are Legato Networker and Veritas Netbackup. They are decent for small (less than 100 systems that need backing up) installations. However, if you want to backup thousands of computer systems and deal with as few backup-servers as possible, then Tivoli Storage Manager is really your only choice. The largest disaster recovery systems in the world use Tivoli Storage Manager. Of course, TSM does come at a hefty price... there is a lot of up front time required when setting it up. You need to know lots of very basic information about the hardware and software that you are going to use TSM with. This then allows for a lot of power in how you deal with that data though. It can manage thousands of terabytes of information storage on thousands of computer systems. It is very powerful. IBM Tivoli Storage Manager used to be called other things in the past...the best known being ADSM -- Adstar Distributed Storage Manager. The main mailing list in the TSM world is still called ADSM-L. Find out more info about it at www.adsm.org. This book is a guide to many of the TSM Internals that a system administrator would need to know. If you are going to be using ITSM/TSM/ADSM... then you should get this book. I highly recommend this book.
