[Dovecot] maildir backup

[Ramon Orrù]

Hi everybody, I'm trying to backup a dovecot instance, and i'm looking 
for a method to "snapshot" dovecot maildir in a properly way, and backup 
whole snapshot in a second step (tar). I read about dsync, end, if i'm 
not going wrong, it dumps correctly also dovecot indexes; is it the tool 
i need? Thank you for any hint. Ramon
