can't make a dump of the mnesia database

How can i make a dump of a mnesia database or table. I get an error if i exacte the example below (i do have full control over the folder 777)

./ejabberdctl backup /var/log/tmp/dump.txt
Can't store backup in "/var/www/log/tmp/dump.txt" at node ejabberd@localhost: {'EXIT',
{error,
{file_error,
"/var/www/log/tmp/dump.txt.BUPTMP",
eacces}}}

./ejabberdctl dump_table /var/www/log/test.txt vcard
Can't store dump in "/var/www/fastguide/tmp/test.txt" at node ejabberd@localhost: eacces

What am i doing wrong?

And is there a way to look in the database?

eaccess is the error code for Permission denied. The user running the command probably doesn't have write permissions for the directories where you tried to store the dump file. The easiest way to check this is by running touch /var/www/log/foo.txt, if it fails then you need another user than can write to this directory.
