Hello, I want to setup a backup mail server, including postfix und cyrus (version 2.3.11). I have tried the following methods to transfer the two directories /var/lib/imap and /var/spool/imap to the backup server: 1st method: 1. stop cyrus on the backup server 2. cp -prfad primary:/var/lib/imap/* /var/lib/imap/ 3. cp -prfad primary:/var/spool/imap/* /var/spool/imap/ 4. chown cyrus:mail /var/spool/imap /var/lib/imap -R 5. start cyrus on the backup server 2nd method: 1. stop cyrus on the backup server 2. rsync -e ssh -avuz primary:/var/lib/imap/* /var/lib/imap/ 3. rsync -e ssh -avuz primary:/var/spool/imap/* /var/spool/imap/ 4. start cyrus on the backup server When I start Thunderbird on both servers, messages that are marked read on the primary server, on marked unread on the backup server. Obviously the seen files are ignored. How do I get an exact copy of the imap server data to the backup server? Thanks for any hints or advice, Stefan ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
