First, I don't see anything attached for us to look over, and my magic 
twanger is on the fritz.

Second, is the tape big enough to be able to hold 5/8ths of the total.

The second is because you should set the autoflush option and let it 
flush that which is sitting in the holding disk on day one which 
would consist of the backups for days 5-8 in addition to the regular 
day 1 backup.

And third, if the dumpcycle is going to be 8 days, then you need at 
least 16 tapes because you don't want to ever get into the situation 
where you are over-writing your only backup of that DLE with a new 
one that fails.
