Re: Backups in HA environments

Hi Steven

A couple of questions:

- What time frame do the tapes have to be available in ?
- Do the tapes HAVE to come from a save conducted on the primary site ?
- Is there any possibility you could courier the saves daily to the 
backup site so they're "already there" ?

A point worth making: if you can't trust the backups on your HA 
machine, then you don't have HA....

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.
