Hi,
I have a PDC running inside a xenserver VM. I need to move this copy to a different hardware.
I made a copy of the original VM but now I need to sync them.
Other then home directories, flexshares. What else?
Can I stop system-mysql on both servers and just rsync?
What about zarafa? Ldap?
Would rsync of system-mysql and directory with attachements do it?
Thanks,

    Don't have zarafa and assume it must maintain the relationship between the original emails and the attachments in the database.
    Does your zarafa have a reliable imap interface? If so. then would hope that imapsync would sync the two mail servers. Use cyrus-imapd and imapsync does a good job of backing up my mail to the backup server using a cron job. Do you use mysql (system or user) for anything other than mail? Is the switch to the stand-by automatic or manual? When switching you would need to stop the copying from master to stand-by first, otherwise all the new data, emails etc on the stand-by would be wiped if the master becomes active again. You are also going to have to consider how users switch to the new ip of the stand-by, or how you switch ips between master and stand-by etc. Probably more to consider! A candidate for DRBD :-)

    As for ldap - wasn't there development for a master ldap and slaves (even multiple slaves)? Think this is probably a professional edition only option.

    You would also need to consider how system configuration changes on the master machine may affect the other. That should at least give food for thought.
