m(d)box - rsync? Hello,I manage a small number of email accounts for a 
voluntary organisation on a shared hosting platform.$ dovecot --version2.3.13 
(89f716dc2)I would like to keep automated local backups, but do not have access 
to doveadm.I have seen a couple of forum posts where users have have suggested 
that using rsync to backup m(d)box folders can corrupt dovecot's indexes, but 
there is no further explanation, and this is apparently not a problem for 
maildir.  Our host seems to use mdbox.Does doveadm provide some sort of 
transaction/locking mechanism to prevent consistency problems?  Others seem to 
recommend using tar but I don't see what difference that should make.Given that 
cpanel backups (provided as tar.gz archives of the home directory) include 
mail/ and seem to be copies of the filesystem at a particular time (though not 
true "snapshots" as such), aren't these just as "safe" as an rsync-ed 
backup?Can anyone confirm/deny/shed any light on the issue(s), if indeed 
any?Many thanks,Gareth_______________________________________________dovecot
