Application-Aware Backups for Oracle on Linux VMs
For standalone Oracle databases running on Linux VMs, you can perform application-aware backups from a VSA subclient, then use the Oracle database agent to restore a database.
Application-aware backups using the Virtual Server Agent are supported for Oracle databases running on Linux VMs in the following configurations:
- Oracle VM and OpenStack hypervisors
- UNIX versions of Oracle that are listed in Oracle System Requirements
Before You Begin
- Review the general requirements for application-aware backups. These requirements apply for all supported hypervisors and applications.
- In a firewalled environment with restricted network settings or where WMI ports are not open, see Remote Installation Requirements for Application-Aware Backups to enable remote installations during application-aware backups.
- Configure credentials to be used for application-aware backups.
- Configure one or more subclients for application-aware backups.
- Review general requirements for application-aware backups and restores.
- Oracle requirements: For Linux VMs running Oracle, ensure that the following requirements are met:
- Data and logs must be on separate volumes.
- lvmetad daemons should not be running.
- The DNS hostnames for Linux VMs must be the same as the machine names for the VMs.
- Logical Volume Manager (LVM) should be configured to use native snaps.
- Ensure that the psmisc package is installed.
To perform backups and restores for Oracle for Linux databases, a user account with admin privileges for the application and database is required.
Include Linux virtual machines running Oracle in a separate subclient under a Virtual Server instance.
Oracle for Windows database logs are automatically backed up as part of application-aware backups. The following methods provide log protection:
- A snap backup of the archive log volume is taken as part of application-aware backups.
- An automatic log backup schedule is created automatically after you run an application-aware backup successfully for the first time. A backup on the Archive Log Subclient runs immediately after the first successful application-aware backup.
- As part of the automatic log backup schedule, logs are backed up before the archive log destination reaches the available disk space threshold (by default, 70%), or at a regular interval (by default, every 24 hours).
Restores for Oracle
See Restoring an Oracle Database to restore a database from an application-aware backup.
From the Oracle Restore Options dialog box, use the following option:
- Click Advanced.
The Oracle Advanced Restore Options dialog box appears.
- On the General tab, select Use FileSystem Restore.
