We're going to have to abandon the idea of duplicating the tapes from the 
HA site back to the primary site. We made a error converting the size of 
the backups. Its actually about 250 GB not 2.5GB. We won't have a large 
enough comm pipe to send those tapes back. 

Although in theory we could use a courier to transport tapes back to the 
primary site, I don't think this will be done. The HA site is basically a 
lights out operation, with no one from our company on site. 

We'll have to present a graceful way to allow our manager to choose 
between her goals of 24/7 availability, and a set of tapes in hand each 
day. We will have to point out that we can do a full system save in about 
90 minutes if the HA site is unavailable, and we have to vacate our 
primary site.
