"doveadm backup/sync" are badly documented
Most documents around there talk abour "dsync", but the modern way is "doveadm backup". This command is not documented in the wiki and there are a few details missing, like how to use it thru SSH.
I am currently doing some tests about how to backup my mdbox. I can do tests in local using:
$ doveadm backup -u jcea -m proveedores/dovecot mdbox:/tmp/aa/
This will "backup" this mailing list mailbox to "/tmp/aa". Good. Lets try thru SSH:
$ doveadm backup -u jcea -m proveedores/dovecot ssh 127.0.0.1 dsync -u jcea mdbox:/tmp/aa/ jcea@127.0.0.1's password: Fatal: Invalid parameter: mdbox:/tmp/aa/ dsync-local(jcea): Error: read(remote) failed: EOF (version not received)
How shoudl I do it?.
$ doveadm backup -h
backup: invalid option -- 'h'
doveadm backup [-u <user>|-A] [-S
I can't find any explanation at all about the different parameters of "doveadm backup".
Same thing with "doveadm sync".

Trying a few things I got here, that works:
$ doveadm -o mail_fsync=never -o mdbox_rotate_interval=99d -o mdbox_rotate_size=10M -o mail_attachment_dir=/tmp/aa/attachments -o mail_attachment_min_size=64k -o mail_attachment_hash=%{sha256} -o mail_location=mdbox:/tmp/aa/:DIRNAME=XxX backup -m 'varios/nosotros' -R ssh 127.0.0.1 doveadm dsync-server
Two things:
I am connecting to myself thru SSH. I want to do a copy of my mdbox with a different configuration. I was not able to transfer that configuration change to thru SSH, so I just reverse the data flow direction (The "-R"): just connect to the regular mailbox_location and bring data here to be stored with a different configuration. This was a kind of enlightment.
You must do "ssh 127.0.0.1 doveadm dsync-server" instead of simply "ssh 127.0.0.1" because you would get this error:
bash: dsync-server: command not found dsync-local(jcea): Error: read(remote) failed: EOF (version not received) dsync-local(jcea): Error: Remote command returned error 127: ssh 127.0.0.1 dsync-server
I guess dovecot is sending the legacy "dsync-server" instead of the current "doveadm dsync-server".
LOOKS LIKE THAT IS A BUG!!.
$ doveadm backup -h backup: invalid option -- 'h' doveadm backup [-u <user>|-A] [-S
] [-dfR] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] <dest> I can't find any explanation at all about the different parameters of "doveadm backup".
Please, document.

That's my task. I hope I'll find the time to write the fine manual until this weekend.
