The nonrewinding tape functionality automatically positions the tape at the end of valid
dump data, which saves time when you perform multiple dump operations.
Backup Server writes an end-of-file label, EOF3, at the end of every dump operation.
Tape Operations
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.
Dump Version Compatibility
Backup Server activates non-rewinding logic only if the label version on the tape is greater than or equal to 5.
