I think you'll want to take this to the "info-cyrus" mailing list rather 
than the cyrus development list.

I've never had problems performing a standard filesystem backup of Cyrus. 
We're not the biggest Cyrus install in the world, but we are doing backups 
and restores of approximately 4.5TB of mail across 3 backend servers.
