3 Configuring Backup and Media Settings

This chapter explains how to configure backup and media settings for an administrative domain.

This chapter contains these sections:

3.1 Configuring Media Families

A media family is a logical classification of volumes that share common attributes. Volumes in a media family share a common naming pattern and policies used to write and keep backup data.

A media family has either of the following types of volume expiration policy types: content-managed (default) or time-managed. Content-managed volumes expire only when every backup piece recorded on a volume has been marked as deleted. Time-managed volumes expire when they pass the duration expressed by the sum of the write window time (if specified), retention period, and volume creation time.

The only default media family is RMAN-DEFAULT, which is a content-managed media family used only for RMAN backups. You cannot delete or rename this media family, although you can modify certain of its attributes.

If you do not specify a media family for a file-system backup, then Oracle Secure Backup defaults to the null media family. In this case, the volume has no expiration date and its write window remains open forever. By default, VOL is used for the volume ID prefix, as in the volume ID VOL000002.

It is useful to create media families for the following backup types:

  • Full backups

  • Incremental backups

  • Off-site backups

    This media family contains volumes with no expiration time. These volumes, which are stored off-site, are intended for disaster recovery or long-term storage.

  • Scratch backups

    This media family is intended for test backups or backup and restore work that occurs outside your usual backup schedule.

This section contains these topics:

Note:

You can also manage media families with the Oracle Secure Backup Web tool.

3.1.1 Displaying Defined Media Families

You can use Oracle Enterprise Manager Database Control 11g (Database Control) to display every defined media family. You must have the display administrative domain's configuration right to view the families.

To display defined media families: 

  1. From the Database Control home page, click Availability.

    The Availability subpage appears.

  2. In the Oracle Secure Backup section, click Assign and Manage.

    The Oracle Secure Backup Domain: domain_name page appears.

  3. Click Setup.

    The Setup subpage appears.

  4. In the Media Life Cycle section, click Media Families.

    The Media Families page appears.

  5. The Media Families page displays a table listing all currently defined media families. For each media family, the table shows:

    • The media family name

    • The volume ID to use with this media family

    • Are volumes in this media family appendable?

    • The write window

    • The retention period

3.1.2 Adding a Media Family

You can use Database Control to create a media family. A media family ensures that volumes created at different times have similar characteristics.

The Add Media Family page contains options for configuring a rotation policy and duplication policy. The options show information only if you have set up a vaulting environment. See Chapter 9, "Vaulting" to learn more about vaulting.

To add a media family: 

  1. Follow the steps in "Displaying Defined Media Families".

    The Database Control Media Families page appears.

  2. Click Add.

    The Add Media Family page appears.

    Description of osb_oem002.gif follows
    Description of the illustration osb_oem002.gif

  3. In Media Family Name, enter a name for your media family.

    Media family names are case-sensitive and must start with an alphanumeric character. They can contain only letters, numerals, dashes, underscores, and periods (no spaces). They can contain at most 31 characters.

  4. In Write Window, enter an amount of time.

    You can choose Seconds, Minutes, Hours, Days, Weeks, Months, Years, or Forever in the list to the right of the Write Window field.

    A write window is the period for which a volume set remains open for updates, usually by another backup image. Every volume in the family is considered part of the same volume set. The write window opens when Oracle Secure Backup writes the first file to the first volume in the set. It closes when the specified period elapses. When the write window closes, Oracle Secure Backup disallows further updates to the volume set until one of these conditions is met:

    • It expires.

    • It is relabeled.

    • It is reused.

    • It is unlabeled.

    • It is forcibly overwritten.

    Oracle Secure Backup continues using the volume set for the next backup operation until the write window closes.

  5. For Retention Policy, select one of the following options:

    • Retain Volume Sets For

      By specifying this option, you indicate that this media family is time-managed and not content-managed. If you select this option, then you must also specify a value in the adjacent field and select a time unit from the adjacent list.

      The retention period prevents you from overwriting any volume included as a member of this media family until the end of the specified time period. If one volume becomes full, and if Oracle Secure Backup continues the backup onto subsequent volumes, then it assigns each volume in the volume set the same retention time.

      You can make RMAN backups to time-managed volumes. Thus, volumes with a time-managed expiration policy can contain a mixture of file-system and RMAN backup pieces.

      Caution:

      If you make RMAN backups to time-managed volumes, then it is possible for a volume to expire and be recycled while the RMAN repository reports the backup pieces as available. In this case, you must use the CROSSCHECK command in RMAN to resolve the discrepancy.
    • Content Manages Reuse

      Volumes that use this retention policy are intended for RMAN backups: you cannot write a file-system backup to a content-managed volume.

      A content-managed volume is eligible to be overwritten when all backup image sections have been marked as deleted. You can delete a backup piece through Recovery Manager (RMAN) or through the rmpiece command in obtool. A volume in a content-managed volume set can expire even though other volumes in the same set are not expired.

  6. In Appendable, select one of the following:

    • Yes

      The media family allows additional backup images to be appended to the volumes.

    • No

      The media family does not allow additional backup images to be appended to the volumes.

    The Media Families page appears with a success message and an entry for your additional media family.

  7. In Comment, enter a description of the media family (optional) and click OK.

    The Media Families page appears with a success message and an entry for your additional media family.

3.1.3 Editing or Displaying Media Family Attributes

You can use Database Control to edit any attributes of a user-defined media family so long as you have the modify administrative domain's configuration right. You can also edit any attributes of the RMAN-DEFAULT media family except for write window or keep volume set.

To display or edit attributes for an existing media family: 

  1. Follow the steps in "Displaying Defined Media Families".

    The Database Control Media Families page appears.

  2. Select the media family you want to display or edit and click Edit.

    The Add Media Family page appears with fields and options set to the existing values for the selected media family.

  3. Make whatever changes you want and click OK.

    The Media Families page appears with a success message and the values for your edited media family.

    Note:

    You cannot change the name of a media family in Oracle Enterprise Manager Database Control. Use the Oracle Secure Backup Web tool or renmf command instead. See Oracle Secure Backup Reference for complete syntax and semantics for the renmf command.

3.1.4 Removing a Media Family

You can use Enterprise Control to delete a media family from the domain. Note that removing a media family does not affect the metadata on tapes that were originally written using that media family.

To remove a media family: 

  1. Follow the steps in "Displaying Defined Media Families".

    The Database Control Media Families page appears.

  2. Select the media family you want to remove and click Remove.

    A Confirmation page appears.

  3. Click Yes.

    The Media Families page appears with a success message and no entry for the deleted media family.

3.2 Configuring Database Backup Storage Selectors

A database backup storage selector associates an RMAN backup with Oracle Secure Backup storage media. For example, you can specify that RMAN backups of archived redo logs from the orcl database should use the orcl_log media family.

You can use Database Control to create a storage selector. Database Control gives the selector a system-defined name. If you want to specify the name for the database backup storage selector, then use the mkssel command in obtool.

This section contains these topics:

Note:

You can also manage database backup storage selectors with the Oracle Secure Backup Web tool.

3.2.1 Displaying Defined Database Backup Storage Selectors

You must have the display administrative domain's configuration right to display storage selectors.

To display defined database storage selectors: 

  1. From the Database Control home page, click Availability.

    The Availability subpage appears.

  2. In the Backup/Recovery section, click Backup Settings.

    The Backup Settings page appears.

3.2.2 Adding a Database Backup Storage Selector

You can use Database Control to create a database backup storage selector. Oracle Secure Backup uses the information encapsulated in storage selectors for a backup job when interacting with Recovery Manager (RMAN).

To configure a database backup storage selector: 

  1. Perform the steps in "Displaying Defined Database Backup Storage Selectors".

    The Backup Settings page appears.

  2. In the Oracle Secure Backup Domain section, click Configure.

    • Incremental

  6. In Copy Number, select a copy number.

    If you leave the Copy Number list at the default (*), then this storage selector applies to all backups.

  7. In Media Family, select a media family.

  8. In Encryption, select one of the following options to indicate the type of encryption.

    • on: The backup data is encrypted, unless it is already encrypted by RMAN.

    • off: The backup data is not encrypted unless either the host or global policy is set to required. This is the default setting.

    • forced off: The backup data is not encrypted, overriding any host-specific encryption settings. This setting does not affect RMAN, which can still encrypt the backup data.

    • software encryption: Uses software encryption to encrypt data instead of hardware encryption.

  9. In Resource Wait Time, enter a value and select a unit from the adjacent list. The default is Forever.

    The resource wait time specifies how long to wait for the availability of resources required by backups. If resources do not become available within this time, then the backup fails.

  10. In the Use Devices section, click Add to specify which tape device to use for this backup.

    If you do not specify any tape devices, then Oracle Secure Backup uses any available tape device in the administrative domain.

    The Use Devices page appears.

  11. If you want to filter the list of tape devices, then enter a tape device name in the Device Name field and click Go.

    In the Search Results table, select a tape drive to add and click Select.

    The Add Database Selector page appears with the selected tape drive in the Use Device table.

  12. Select the tape drive or drives to use and click Select.

    • Since

      This option specifies a starting point for the time period that the report covers. Select a day of the week from the adjacent list and a time in the hours and minutes lists.

  8. Select report options. You can enable or disable each of the following options independently of other report options:

    • Backup jobs

      This option specifies whether file-system backup jobs should be included in the report.

    • Oracle backup jobs

      This option specifies whether RMAN backup jobs should be included in the report.

    • Scheduled jobs

      This option specifies whether all jobs waiting to be processed in the scheduler should be included in the report. A scheduled job is a job that has yet to be run.

    • Subordinate jobs

      This option specifies whether the report should include subordinate jobs.

    • Volume duplication jobs

      This option specifies whether volume duplication jobs should be included in the report.

    • Restore jobs

      This option specifies whether file-system restore jobs should be included in the report.

    • Oracle restore jobs

      This option specifies whether RMAN backup jobs should be included in the report.

    • User jobs

      This option specifies whether the report should include user-initiated jobs. If this option is set to no, then the summary only shows scheduled jobs.

    • Superseded jobs

      This option specifies whether the report should include all jobs that have identical criteria.

    • Catalog backup jobs

      This option specifies whether the report should include information about catalog backups. Catalog backups are also listed in summary reports that include information on backup jobs. However, they are mixed in with other backups and not marked specifically as catalog backups. This option is intended to help monitor the status of catalog backups independently of other backup jobs.

  9. Click OK.

    The Configure: Job Summaries page displays a success message, and your job summary appears in the list.
