When a new dump is performed, Backup Server performs a scan for the most recent EOF3 label. The pertinent information is saved and the tape is positioned forward to the beginning of the next file on tape. This is the new append point.
If the EOF3 label is not found or any other problem occurs, Backup Server rewinds the tape and scans forward. Any error that occurs during these steps does not abort the dump operation, but causes Backup Server to default to rewind-and-scan behavior. If the error persists during the rewind and scan, the dump command aborts.
