Does anyone know more about the recycle bin - don't seem able to access from the wiki, and (I guess any deleted wiki pages or attachments go into it?) the code snippet didn't seem to empty it from the database - any ideas how to empty it? -----Original Message----- From: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] On Behalf Of Guillaume Fenollar Sent: 13 January 2012 08:55 To: XWiki Users Subject: Re: [xwiki-users] Backing up xwiki using mysql Hi Richard, Here a quickfix: use max_allow_packet directive directly into your dump command. mysqldump --max_allowed_packet=512m nms_wiki > backup.sql If you want to understand this more, you should try to change my.cnf, in the section [mysqldump] (just like there is [client], you could create it if you haven't) and try the command without putting max_allowed_packet into the command, it should work too.
