Dumping and restoring database
Hi,



I found some information on
http://meta.wikimedia.org/wiki/How_to_move_a_MediaWiki_Database
regarding dumping and restoring the sql database. The dump seems to
work fine. However, when I try to restore the database, I receive the
error, ERROR 1050 at line 11: Table 'archive' already exists



bash-2.05b$ mysqldump -u root -p wikidb > /tmp/wikidb.sql

Enter password:

bash-2.05b$ ls -la /tmp/wikidb.sql

-rw-r--r-- 1 wikiuser wikiuser 377369 Oct 6 13:34 /tmp/wikidb.sql

bash-2.05b$ mysql -u root -p wikidb < /tmp/wikidb.sql

Enter password:

ERROR 1050 at line 11: Table 'archive' already exists

bash-2.05b$



How can I restore the database? Also, are there any other files which
should be backed up?



Thanks,

Chuck Bishop

Were you restoring into a blank, newly created database or one that
already had a wiki in it?

If the latter, you need to either manually remove the old tables or
make your dump with the --add-drop-tables or --opt options to
mysqldump.

Uploaded images and any config or customized code files that you want
to keep.

Thanks Brion. I was trying to restore over an existing database and
your suggestion seemed to work fine.

Is there any potential problems importing a backup database over an
existing one?

Thanks,
Chuck
