Package: ejabberd
Version: 18.12.1-2
Severity: normal
Dear Maintainer,
I have a problem trying yo backup ejabberd database.
I'm using ejabberd (18.12.1-2) with debian buster.
When I do (as root):
ejabberdctl backup /tmp/ejabberd.backup
I don't get any errors, but there is no /tmp/ejabberd.backup file
neither.
journalctl show some lines related with apparmor, although they are
supposed to ALLOW the operations:

The fact is that there is no /tmp/ejabberd.backup file
According to /etc/apparmor.d/usr.sbin.ejabberdctl:
/var/backups/ rw,
/var/backups/ejabberd** rwlk,
So I tried:
ejabberdctl backup /var/backups/ejabberd.backup
and I get this error:
Can't store backup in "/var/backups/ejabberd.backup" at node
ejabberd@localhost: {'EXIT',
{error,
{file_error,
"/var/backups/ejabberd.backup.BUPTMP",
eacces}}}
because /var/backups/ has 755 permissions and is owned by root:root.
I created a directory in /tmp, owned by ejabberd but it did not worked
neither.
The only way I managed to make a backup was in /var/run/ejabberd (it is
owned by ejabberd, and also with "rw" in
/etc/apparmor.d/usr/sbin/ejabberdctl)
ejabberdctl backup /var/run/ejabberd/ejabberd.backup
The documentation (/usr/share/doc/ejabberd/README.Debian.gz says that
backups are stored in /var/backups when ejabberd is upgraded or
restored. I didn't check if this is working or is it also affected by
this problem.
There is not (or at least I didn't find) a proper place to store
backups.
I think it should be documented where to store backups, or have and
specific directory for backups that works.
Regards and thank you.
