To phrase it slightly differently, with that "complete" set, you will be able to recover/restore to the state of the most recent of the 5 amdumps. For some DLE's the level 0 will be on that 5th tape. For other DLE's, there will be a level 0 on an earlier tape and incrementals between that and the 5th tape. But all DLE's should have a level 0 somewhere in those 5 tapes and incrementals as needed upto the date of the most recent tape. -- Jon H.
