Tivoli Field Guide - Full-Incremental Rotations Using IBM Tivoli Storage Manager
 White paper
 
Abstract
Administrators backup computers for two reasons. First, backups protect against the failure or corruption of storage media on a computer system. In the event of such a failure, the data can be restored from a backup kept on-site and the business can continue to function. Second, backups protect data against the complete loss that can result from natural disasters such as floods and hurricanes. In the event of these types of disasters, the administrator will restore data from a copy that is kept in a secondary or off-site location.
There are numerous applications and methodologies that allow administrators to produce both on-site and off-site backups of data. The simplest of these relies on producing two full backup copies of the data; one for storing on-site and one for taking off-site. Other applications, such as IBM Tivoli Storage Manager, allow the administrator to use more sophisticated methodologies for creating and managing backup data. Typically, these methodologies are employed to reduce the amount of hardware and time it takes to produce the backup and to effectively manage the retention and restoration of the backup data once it exists.
As the amount of data that needs to be backed up grows, administrators must often consider these more sophisticated methodologies in order to meet backup time constraints, reduce the costs of backup hardware, or more fully protect backed up data. Unfortunately backup, retention, and disaster recovery policies are often written in terms of the ordinary functionality of less sophisticated products. The backup architect or administrator must then take these policies and translate them into the features and functionality of a particular backup tool such as IBM Tivoli Storage Manager.
This field guide will describe one of the more popular of these backup methodologies; the Full-Incremental rotation. It will describe the features that are available in Storage Manager for performing backups and it will provide several different ways to implement the Full-Incremental rotation using Storage Manager functionality. In conclusion, the guide will discuss the advantages of using Storage Manager policy and make recommendations on the best ways to perform backups using Storage Manager.
