What is backup and restore?
Backup and restore is a process where you can backup data from previous version of PowerVC and restore the same to the newer version while ensuring continuity of operations, better performance, and lower infrastructure costs.

During backup procedure, PowerVC backup stores copies of database and PowerVC related conf files. Creating a backup is critical to protect your data in the event of system failure or file corruption. In PowerVC 2.0.2, you can choose 'active backup' option by using
powervc-opsmgr backup -c <cluster_name>.
During restore procedure, PowerVC copies back the PowerVC related conf files and imports DB dump taken from backup system.
Perform these steps to restore PowerVC.
- Copy the backup file to the targeted single node PowerVC version 2.0.2 system.
- Run powervc-restore to restore PowerVC backup tar.
Example: powervc-opsmgr restore -c <cluster_name> -b <absolute_path_of_backup_tar>
You must restore only active backup.
In case of any failure during restore, use
powervc-opsmgr restore -c <cluster_name> -r to bring back the restore environment.
