Hi there! It seems that # doveadm backup -v backup -fu $MUSER mdbox:"$BKPDIR/$MUSER/mdbox" doesn't backup all messages stored in alternate storage.
mail_location = mdbox:~/mdbox:ALT=/srv/mail/slow/vmail/%n/mdbox I don't know how to debug this. The sizes of the mailboxes in the filesystems of user C are strange: ~/mdbox: # du -sm 2169 ALT: # du -sm 25252 backup: # du -sm 2658 This is with dovecot 2.2.9 on Ubuntu x86_64 14.04.2 LTS. Is this a bug or am I doing something wrong? How can I test if messages stored in the alternate storage are successfully backed up? Thanks Lars
