doveadm backup Error: Mailbox INBOX sync

[Pierre Sablé]

Hi,

the command  "doveadm  backup -u {user@mail} 
maildir:/home/backup/{user@mail}/mails/" returns the following error :


dsync(user@mail): Error: Mailbox INBOX sync: mailbox_delete failed: 
INBOX can't be deleted.



...and nothing in dovecot logs

 dovecot actual version 2.3.15


I did not have this pb in dovecot 2.3.2

/Should this be considered a bug report?/

Re: doveadm backup : Error: Failed to access mailbox

[Laura Smith]

FYI, found the solution.

It seems doveadm can't cope with brackets in mailbox names.

I moved the user's mails into non-braketed, deleted the bracketed and doveadm 
backup worked fine after that.

doveadm backup : Error: Failed to access mailbox

Hi All,

So close and yet so far.  ;-(
Have been migrating users from an old Dovecot server to a new one.
All of the users have doveadm backup'd perfectly, except for one !

What does the below mean ?

doveadm backup: Error: Both source and destination mail_location points to same directory

[Martin Johannes Dauser]

Hello!

I'm using 2 namespaces, "inbox" for INBOX and it's subfolders and
"special" containing folders like Sent, Junk or Drafts.  Though both
use mdbox I decided to represent those namespaces in different
locations "mdbox:~/mail" and "mdbox:~/mail_special_folders". The main
reason to use 2 namespaces was to keep special_use folders out of INBOX
by using the prefix attribute -- it's rather cosmetic. 

├── INBOX
│   ├── SubFolder1
│   ├── SubFolder2
│   └── SubFolder3
├── Sent
├── Trash
├── Drafts
├── Junk
├── Templates
├── This is Ham
└── Report Spam

Now I want to export the emails of some former users to common known
maildir or mbox format to be able to hand them over on CD. The problem
is that a conversion with doveadm backup fails. I guess this is due to
namespace special which is configured with a manual location attribute
instead of utilising mail_location. But even telling doveadm to backup
only one namespace leads to the identical error (extract of debug
message at bottom). 

As this is a RHEL7 server, the dovecot version is an old 2.2.10 and I
don't expect software debugging -- I just ask if I did some
misconfiguration or a failure in the command.
I already thought of merging the locations of both namespaces. Yet, I'm
not sure how to achieve this. 

>From /etc/dovecot/conf.d/10-mail.conf

mail_location = mdbox:~/mail

namespace inbox {
  type = private
  hidden = no
  ignore_on_failure = no
  inbox = yes

  location = mdbox:~/mail_special_folders

This is probably problem on the other end.
