Backing up IBM Power® Virtualization Center data
Use the powervc-backup command to back up your essential PowerVC data. You can then restore to a working state in the event of data corruption or a disaster.
The powervc-backup command is in the /opt/ibm/powervc/bin/ directory.
For syntax and options, run powervc-backup --help
.
The
following data is backed up:
- PowerVC databases, such as the nova database where information about your registered hosts is stored
- PowerVC configuration data, such as /etc/nova
- SSH private keys that are provided by the administrator
- Glance image repositories
Important: Most PowerVC services
are stopped and all other users are logged off from PowerVC until
the operation completes.
Complete
the following steps to back up PowerVC data.When the backup operation completes, new file powervc_backup.tar.gz is
placed in a new time stamp subdirectory of the target directory. For
example, a potential file path is /var/opt/ibm/powervc/backups/201391214289350413/powervc_backup.tar.gz.
You can then leave the archive there or move or copy it to another
directory as needed.
Note: If an error occurs while running powervc-backup,
check for errors in the powervc-backup logs in /opt/ibm/powervc/log.
Consider regularly, for example on a daily basis, backing up your PowerVC data as part of a broader system backup
and recovery strategy. If you want to regularly back up, use your operating system's scheduling tool
to set the powervc-backup command to run on a schedule. Target off-peak intervals
when few or no other operations are running in PowerVC.
Active backup of PowerVC
You can use powervc-backup
with the --active
option to take backup of PowerVC management
server even when operations are in progress.
