This chapter explains how to configure backup and media settings for an administrative domain.
This chapter contains these sections:
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), the retention period, and the 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.See Also:
"Media Families"To display every defined media family with Oracle Enterprise Manager Database Control 11g (Oracle Database Control 11g):
From the Oracle Database Control 11g home page, click Availability.
The Availability subpage appears.
In the Oracle Secure Backup section, click Oracle Secure Backup Device and Media.
The Oracle Secure Backup Device and Media: Administrative Server page appears.
In the Resources section, click the number to the right of Media Families.
The Media Families page appears.
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
Each entry in the table also has a select option, and the page has Edit, Remove, and Add options. These are described in the following sections.
To add a media family with Oracle Database Control 11g:
Follow the steps in "Displaying Defined Media Families".
The Oracle Database Control 11g Media Families page appears.
Click Add.
The Add Media Family page appears.
Enter a name for your new media family in the Media Family Name field. 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.
Enter a value for the media family write window in the Write Window field. 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 of time 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 the first file is written to the first volume in the set and closes after the specified period of time elapses. When the write window closes, Oracle Secure Backup disallows further updates to the volume set until one of the following 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.
Select one of the following retention policies:
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.
Retain Volume Sets For
By specifying this option, you indicate that this media family is time-managed rather than 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.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 new media family.
You can 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 with Oracle Database Control 11g:
Follow the steps in "Displaying Defined Media Families".
The Oracle Database Control 11g Media Families page appears.
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.
Make whatever changes you want and click OK.
The Media Families page appears with a success message and the new 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 obtoolrenmf command instead. See Oracle Secure Backup Reference for complete syntax and semantics for the renmf command.To remove a media family with Oracle Database Control 11g:
Follow the steps in "Displaying Defined Media Families".
The Oracle Database Control 11g Media Families page appears.
Select the media family you want to remove and click Remove.
A Confirmation page appears.
Click Yes.
The Media Families page appears with a success message and no entry for the deleted media family.
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 Oracle Enterprise Manager Database Control to create a database backup 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.
