Thanks Guillaume - it worked a treat - I'll setting up the my.cnf another time, but at least I can backup now! 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: [email protected] [mailto:[email protected]] 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.

Hi All,

Running ... mysqldump nms_wiki > backup.sql

Returns ... mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table `xwikiattrecyclebin` at row: 2

I did have some rather large import attachments - which I deleted but they seem to have gone into the recycle bin - so I used the code snippet http://extensions.xwiki.org/xwiki/bin/view/Extension/Empty+Trash+Bin

To supposedly empty the bin, but get the same error above when I try and dump the database seeming to indicate the recycle bin isn't empty.

Tried increasing the max_allowed_packet when I run mysql, but doesn't seem to have any affect - is something overriding it? We're running on Solaris.

Any ideas/help would be appreciated so I can backup the wiki successfully on mysql!!!!

Thanks.

Regards,
