Backing up the Virtual I/O Server by using IBM Tivoli Storage Manager incremental backup
You can back up the Virtual I/O Server at any time by performing an incremental backup with the IBM® Tivoli® Storage Manager.
About this task
Perform incremental backups in situations where the automated backup does not suit your needs. For example, before you upgrade the Virtual I/O Server, perform an incremental backup to ensure that you have a backup of the current configuration. Then, after you upgrade the Virtual I/O Server, perform another incremental backup to ensure that you have a backup of the upgraded configuration.
Before you start, complete the following tasks:
- Ensure that you configured the Tivoli Storage Manager client on the Virtual I/O Server. For instructions, see Configuring the IBM Tivoli Storage Manager client.
- Ensure that you have an mksysb image of the Virtual I/O Server. If you plan to restore the Virtual I/O Server to a different
system from which it was backed up, then ensure that the mksysb includes information about
user-defined virtual devices. For more information, see the following tasks:
- For instructions about how to create an mksysb image, see Backing up the Virtual I/O Server to a remote file system by creating an mksysb image.
- For instructions about how to save user-defined virtual devices, see Backing up user-defined virtual devices by using the backupios command.
Procedure
To perform an incremental backup of the Virtual I/O Server,
run the dsmc command.
For example,
dsmc -incremental sourcefilespec
Where
sourcefilespec is the directory path to where the mksysb
file is located. For example, /home/padmin/mksysb_image
.
