<p>Hello,<br>
<br>
I also have issues using Dovecot Backup.<br>
<br>
I am trying to Backup (or possibly Sync - one way) a single user
IMAP account from a remote server, unknown type, to my own server.<br>
<br>
For that purpose, I defined the following parameters :<br>
<br>
<font face="Courier New">imapc_host = <</font><font
face="Courier New"><font face="Courier New"><font face="Courier
New">host name</font></font>><br>
imapc_user = </font><font face="Courier New"><font
face="Courier New"><user name><br>
</font>imapc_password = <password><br>
imapc_features = rfc822.size</font><br>
</p>
<p><font face="Arial">(<font face="Courier New"><user name></font>
has format: <font face="Courier New"><a class="moz-txt-link-abbreviated" href="mailto:name@example.com">name@example.com</a></font>,
and <font face="Courier New"><host name></font> is the
name of the imap remote server that I use for getting mails)</font></p>
<p>… and then I issued the following command:<br>
<br>
<font face="Courier New">doveadm backup -R -u <user name,
format <a class="moz-txt-link-abbreviated" href="mailto:name@example.com">name@example.com</a>> imapc:</font><br>
</p>
<p>... but doing this, I get the following answer:</p>
<p><font face="Courier New">dsync(<user name>): Info: imapc(<host
name>:143): Connected to <host IP address>:143 (local
192.168.1.2:52940)<br>
dsync(<user name>): Error: Failed to initialize user:
namespace configuration error: Namespace mail/ can't have
alias_for= to a different storage (different root dirs)</font><br>
<br>
How can I solve this?</p>
<p>If there is something not matching between servers, I may
eventually change configuration on my side, but I think I would
first have to know which feature(s) I have to know from the remote
server in order to create the matching one on my server.<br>
</p>
<p>Is there a way to list all relevant data coming from the remote
server?<br>
<br>
Also:</p>
<p>Doing this, is it necessary that the source user name be the same
as the destination user name? Is it possible to backup an IMAP
account to a user account having a completely different name?<br>
<br>
Regards,<br>
