Data Protection: Specifying How Long Data Is Kept on the Media

Configuring protection policies is extremely important for the safety of your data and for successful management of your environment. See the HP OpenView Storage Data Protector Concepts Guide for more detailed information on how to define these policies.

Based on your company data protection policies, you have to specify how long your backed up data is kept on the medium. For example, you may decide that data is out of date after three weeks and can be overwritten during a subsequent backup.

NOTE	Due to operating system limitations, the latest protection date that can
	be set is Jan 18th, 2038.

You can specify data protection in different places. Different combinations are available, depending on whether you are running an interactive backup, starting a saved backup specification, or scheduling a backup. The default value is Permanent.

•Interactive backups

When configuring an interactive backup, you can change the default data protection for the entire backup. See Figure 5-28 on page 229. Additionally, you can specify different data protection periods for individual backup objects. The protection that is specified on the backup object level overrides the default protection setting. See Figure 5-29 on page 230.

•Backups using a saved backup specification

When starting saved backups using the GUI, the data protection is applied as described for interactive backups.

When starting saved backups using the CLI, you can also specify data protection. This will override all data protection settings in the backup specification.

•Scheduled backups
