Implementing a media rotation policy

What is a media rotation policy?

A media rotation policy defines how media are used during backup, including the following. In defining a media rotation policy, answer the following questions:

•How many backup generations are needed?

•Where are media stored?

•How often media are used?

•When can media be overwritten and re-used for new backups?

•When are media old enough to be replaced?

Traditional backup strategies used with older backup tools required a thoroughly planned and well defined media rotation policy controlled by the administrator rather than a backup application. With Data Protector, you can implement a rotation policy by specifying usage options such that media selection for subsequent backups is done automatically.
