How to Archive a tape

You don't do anything to archive the tape. What it is saying is when you do a incremental backup that the archive atribute is cleared which means that it will not backup that file again untill the next normal backup. So if you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets in order to restore your data.

Your best bet would be to Run a normal back up every week and a differential backup every day or other day depending on your needs, that way when you restore you only have to restore the last normal as well as the last differential backup. Because the Archive atribute is not cleared when you run a differential backup.

Previous answer is correct but just another thought, why don't you just do a full backup every night. This way if anthing ever goes wrong you only have to use one tape to get all data back.
Have you ever tried to get someones data back when you have to go through loads of tapes!!!! it's a nightmare!!!!
