If you think there is not enough space for the next backup on the current tape or disk of your backup set, you can tell Retrospect to ask for a new one.

To skip to a new member, click backup sets from the Retrospect Directory's Configure tab. In the backup set selection window, select your nearly-full backup set and click Configure. In the window that appears, click the Options tab and click the Action button and select Skip. The next time Retrospect adds files to that backup set it will ask for new media, in effect skipping over the blank space at the end of the current member.

If this situation arises frequently, consider using Retrospect's Automatic Skip to blank media preference. When this preference is on, Retrospect automatically uses any erased media if the current member is not available.

You might also consider purchasing a tape autoloader, a backup device which holds a magazine of many tapes. When one tape fills, Retrospect uses an empty tape from the magazine.
