So the various "letters" of the cyrus hashing are each broken out into their own full backup. Example out of /var/cyrus/mail/ the subdir A-K are in one stream, L-Q in another, etc. I'm not an NBU admin so I dunno why this is more efficient but it worked great. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
