Restore logical log files

When you perform a mixed restore, you must restore all the logical-log files backed up after the last level-0 backup.

When you perform a full restore, you can choose not to restore logical-log files. When you do not back up your logical-log files or choose not to restore them, you can restore your data only up to the state it was in at the time of your last backup. For more information, see Back up logical-log files with ontape.

To restore the logical logs, use the ontape -l command.
