That's going to take a nice chunk of space on our server but
its manageable. Does your project have any funding to offset the costs of
having us do the backups? I can give you an estimate for that if you'd like.

We tend to retain more backups ourselves but we can have a specific
schedule for your backups that meet your needs. We currently use SSL
enabled connections so we'll have to give you some keys to get it to work
with our setup. Do you have any special FileSet filters you use so you
don't backup stuff like logs?

*nods* Currently restores have to be initiated by us but we are working
towards creating access to work around that. Will this be a problem?
