http://wiki2.dovecot.org/Tools/Dsync

dsync should do it , but be aware from dsync bugs in some versions
do heavy testing before doing something live, for many users do i.e with
bash script

export your users from sql to a file, or use live query

for i in `cat user.lst`
do
dsync .....
done

for avoid acl and quota problems

dsync -o plugin/acl= -o plugin/quota= -u ....

perhaps look at

http://sys4.de/de/blog/2013/07/20/fallstricke-mit-acl-und-quota-bei-backup-mit-dsync-dovecot/

be aware of, if  use zlib plugin all backup mails get compressed too
