Just wondered if someone could clarify quickly.
I've got multiple servers storing email, and as I'm migrating the MX records from server to server, I want to ensure consistency by means of rsync.
My plan is to run
rsync -az on the new server, grabbing any messages that might still find it's way to the old server.
I'm still new to using it like this, but as I understand
rsync, it's incremental.
That said, I know the "a" option evaluates to a lot of other options, so I just want to make sure that I'm not going to cause files on the new server that don't exist on the old one to be deleted as a result of using this command.
Also, if there's a better way of doing this, so that both the new and old server are entirely in sync regardless of where new messages might appear, please let me know.
Thanks in advance!
