Configuring a snapshot policy using a share on the NetBackup appliance (Copilot)
Note:
This feature requires a NetBackup appliance running software version 2.7.1 or later.
Use the following procedure to configure an Oracle snapshot policy that uses or options. This procedure uses the Oracle Intelligent Policy, which makes configuration easier.
To configure a snapshot policy using a NetBackup appliance share
- Open the policy you want to configure or create a new policy.
Do not use the Policy Configuration Wizard when performing this procedure.
- Select the Attributes tab.
- Select Oracle as the policy type if this policy is new.
- Select a policy storage unit from the Policy storage list.
Policy storage
Oracle combines snapshots (proxy) and stream-based backups as part of the same backup. The storage that is indicated here is used for the stream-based part of the Database Backup Shares or Whole Database - Datafile Copy Share backup.
Select a storage lifecycle policy that is configured to contain the stream-based (non-snapshot) part of the database backup. The storage must use a storage lifecycle policy that is configured for non-snapshot backups.
- Select Perform snapshot backups.
- Click Options to choose a snapshot method.
When you use the Database Backup Shares or Whole Database - Datafile Copy Share options, remote_vxfs is the only valid snapshot method.
Note:
If there is more than one backup share that is associated with the database instance, then Maximum Snapshots should be set to number of recovery points you want multiplied with number of backup shares. Example: If you want three recovery snapshot points and the database instance is associated with two backup shares then Maximum Snapshots should be set to 6.
- Select Retain snapshot for Instant Recovery or SLP management.
- Select the Schedules tab.
- Click New.
- Configure a Full schedule for the database backup shares.
Type of backup: Select Full Backup. The Full Backup is used for both the snapshot part of the database and the non-snapshot (stream-based) part of the Oracle database.
Override policy storage selection: Enable and select the SLP that is configured for a snapshot. (A snapshot SLP is one in which the first operation is a snapshot operation.) This option must be enabled so that the schedule storage overrides the policy storage with a snapshot SLP.
Retention: The retention for the streamed data is based on the non-snapshot SLP that was indicated as the Policy storage in Step 4.
The non-snapshot SLP specified on the policy storage in Step 4 determines the retention for the streamed data.
The snapshot SLP that is specified as the schedule storage (Override policy storage selection) determines the retention for the snapshot data.
When Database Backup Shares or Whole Database - Datafile Copy Share is selected, it is recommended that an SLP is set up to backup from the snapshots and copy snapshots to a storage unit. NetBackup retains the snapshot backup image on disk for later use in SLP management.
Click OK to save the schedule.
- (Optional) On the Schedules tab, configure an Archived Redo Log Backup schedule for the archived redo logs.
- Select the Instances and Databases tab and specify the instances to back up. The policy must include at least one instance. To continue to use the Oracle Intelligent Policy method, select either Protect instances or Protect instance groups.
- On the Backup Selections tab, use the radio button to select Database Backup Shares or Whole Database - Datafile Copy Share options.
- (Optional) Configure other attributes and add any additional schedules.
