Question Answer
I used the checkpoint restart option for my backups. During one of my backups, a Microsoft cluster failover occurred. Multiple backup sets were created. When I try to verify or restore using these backup sets, an "Unexpected End of Data" error occurs on the set that contains the data that was backed up prior to the failover. Why does this occur? Is my data safe? You received this error because failover occurred in the middle of backing up the resource, therefore the backup set was not closed on the media. However, the objects that were partially backed up in the first backup set were completely backed up again during restart, ensuring data integrity. Therefore, all of the objects on the media for the given backup set should still be restored and verified.
I clustered a central administration server with a managed Backup Exec server. Now the device and media service on the managed Backup Exec server fails. Why? This occurs when the managed Backup Exec server becomes the active node and attempts to connect to the Backup Exec database on the central administration server, which is no longer available. To correct this, you must use the Backup Exec Utility (BEUTILITY.EXE) or reinstall the managed Backup Exec server to become a central administration server.
