So, it turned that there were two .vbks archived to tapes. Not one, as you told me originally.

The described behaviour is expected. If the .vbk is still present on disk, but got removed from tapes, VB&R will try to copy it anew. Therefore, it's recommended to have tape retention longer than the disk one.
Anyway, ability to copy always the latest full backup will be added in version 9, if that's what you're looking for.
