[rt-users] RT 3.6.4 MYSQL Backup

Sorry I should of been more clear,

I have RT 3.6.4 running on an ubuntu machine and backing up the catalog using the Mysql Administrator.  When I am restoring it I am restoring on to a windows xp pro machine running a mysql server.  I have tried restoring attachments after and before just by itself with no luck.

How would I set the max_allowed_packet option under windows? I have access to the console and am using WAMP to run my mysql server.

Yes, like drew said, this can also be the problem, i remeber from our last move.

We increased the max_allowed_packet option massivly, but also without success. We did the trick by dumping only the attachments table and restored them later. Was working fine.

I was thinking that it might be the max_allowed_packet option my.cnf. 

Recent versions of MySQL seem to export the tables in what my office has

begun to refer to as "massive dumps," that is, One insert statement for

each table.

One other option would be not exporting the data in binary format, IIRC.
