B Further information

In this appendix

This appendix provides additional information about some of the aspects of Data
Protector concepts, including backup generations, examples of automated media
copying, and internationalization.

Backup generations

Data Protector provides a time/date related protection model. It is easy to map a
generation-based backup model to the time-based model, assuming regular backups
are done.
What is a backup generation?
A backup generation, shown in
and all incremental backups based on this full backup. When the next full backup is
done, a new backup generation is created.
Backup generations help you to know how many full versions of backed up data you
have. For a successful point-in-time restore, you need at least one backup generation
(a full backup and all incrementals to that point-in-time). Keep more than one backup
generation, three for example, depending on your company policies for data
protection.
