hi,
i´m looking for a strategy to synchronize the primary mailserver to a
backup/fallback server. i´ve read an article about backup strategy in the
cyrus wiki. but is there any other way to do this? e.g. with an internal
component of cyrus?
scenario:
a mail is stored in inbox on primary server.
documenting such a setup in the Cyrus Wiki.
Regards,
Torsten

But this will just provide the HA filesystem, won't it?

Firstly, hello to the list.
drbd is a file system replication program.
Search for rolling replication. Though I failed to get it working
reliably ...
Do you mean this stuff here:

Is this officially supported / endorsed?
I learned that Cyrus IMAPd (for whatever reason) is quite picky on
filesystems. From the FAQ:
