Hi again!
"du" was misleading me.
Most files take 10M in filesystem but are actually only some byte or kilobytes
in size.
This is the result:
# du -h --apparent-size
2,1G.
# du -h
25G .
So my conclusion the backup misses some messages was wrong.
Sorry for the noise

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 use
