Help backup mails from one dovecot server to another dovecot server

Hi to all i'm running two Dovecot servers version 2.2.15 both Server A 
and Server B
Server A is in production instead Server B is ready to start as a 
replacement
My goal is replicate through doveadm backup command mails from Server A 
to Server B
but when i execute following command in Server B error happens

doveadm -vvv -D backup -R -u davide.marchi at mail.cgilfe.it imapc:

dsync(davide.marchi at mail.cgilfe.it): Error: Couldn't delete mailbox 
INBOX: INBOX can't be deleted.

Below are servers' config
