Re: qmail-ldap and GFS

We have multiple nodes each storing the email locally, a backup is made 
to a central backup server. If a node fails we have a script that will 
create the accounts that were on that node onto another node (so sending 
and receiving will work) then we restore the account from the backup. 
The impact to the end user is that they will briefly being missing all 
their old email but then it will just suddenly 'reappear'.
