Configuring a snapshot policy with Instant Recovery for NetBackup for SAP
The following procedure describes how to configure a snapshot policy with Instant Recovery and optional snapshot retention and off-host backup. For information on standard snapshot policies, see the following topic.
See Configuring a snapshot policy for NetBackup for SAP.
To configure a snapshot policy with instant recovery for NetBackup for SAP
- (UNIX or Linux) Perform the prerequisite configuration steps.
See Prerequisites for instant recovery backups (UNIX or Linux).
- Open the NetBackup web UI.
- Open the policy you want to configure.
- Select the Attributes tab.
- Select the SAP policy type.
- Select a policy storage unit from the Policy storage list.
Select a policy storage unit in this step even if you plan to select Snapshots only later in this procedure. NetBackup for SAP uses this storage unit to back up the profile files and configuration files that are backed up in brbackup phase 2.
- Select Perform snapshot backups.
- (Optional) Select Snapshot options to choose a snapshot method.
By default, NetBackup chooses a snapshot method for you. To choose a snapshot method, click auto (the default) or click one of the methods that are presented in the list.
The snapshot method that you can use depends on your hardware environment and software environment. Only certain snapshot methods are supported in certain environments. See the NetBackup NAS Administrator's Guide and the NetBackup Snapshot Manager for Data Center Administrator's Guide. Also see the Hardware and Cloud Storage Compatibility List (HCL).
You can configure only one snapshot method per policy. For example, assume that you want one snapshot method for clients a, b, and c, and a different method for clients d, e, and f. Then you need to create two policies for each group of clients and select one method for each policy.
- (Optional) Select Perform off-host backup.
By default, the client that hosts the database performs the backup. If you want to reduce the I/O processing load on the client that hosts the database, specify an alternate client to perform the backup.
- (Conditional) Select an off-host backup method.
The following off-host backup methods are available:
Alternate client (UNIX and Windows clients)
If you select Alternate client, also specify the name of the client to perform the backup. This option may require additional configuration. The alternate client must be a client that shares the disk array.
Data mover (UNIX clients only)
See Configuring a NAS snapshot policy for NetBackup for SAP on UNIX/Linux.
- Select the Schedules tab.
- Select Add.
- Configure an Automatic schedule for the database files.
These files are backed up in brbackup phase 1.
- Go to Instant Recovery and select Snapshots only.
This setting suppresses NetBackup's default behavior, which is to copy the snapshot to a storage unit. When you select Snapshots only, NetBackup creates the on-disk snapshot copy of the database, but it does not copy the snapshot to a storage unit. The on-disk snapshot becomes the only backup copy. Note that the on-disk snapshot is not considered to be a replacement for a traditional backup.
- Configure an Application backup schedule that backs up profile and configuration files, which are backed up in brbackup phase 2.
NetBackup for SAP copies the profile files or configuration files to the storage unit you select.
- On the Clients tab, specify the clients to be included in this policy.
- On the Backup selections tab, specify a backup script.
- Configure other attributes and add any additional schedules and backup selections.
