It sounds like something happened to the vBackup datastore (vBackup.xml in the vBackup application directory) that has caused it to become corrupted. Maybe a job was processing and was trying to save information to the datastore when the power failed?

The best thing for you to do is probably to reinstall vBackup. This will give you a clean datastore file that you can import the backup datastore file into. Once you have vBackup installed and the backup datastore imported you should see all of your host servers, virtual machines and backup jobs. vBackup will also discover all of the existing backups, but you will need to cleanup (or remove the old backups from inventory). The discovered backups will be marked as "unmanaged". Simply right-click on them and click "Set as Managed" to add them back to inventory.

Also, it might be a good idea to make another backup of the vBackup.xml file once you have everything set back up.
