If 2nd tape contains differnet backup format then you get this type of error. I mean to say if previosly backup taken using tar or cpio and now using fbackup.
Next time u will not get this warning.

It's not an ERROR, it's a WARNING. There is a difference. This WARNING is just saying that there is no fbackup header on this tape. That is normal if the tape has never been used by fbackup before.

It should not cause you any problems when restoring.

Yogi,

Very common warning when you are using the tape for the first time.

Very well supported by Bill's reply in this thread.
