Rebuilding everything

The above methods should be able to fix data records in SMW in most cases. However, it is conceivable that some erroneous content of the SMW storage still persists for some reason. In this case, it makes sense to completely delete and reinstall the database structures of SMW before refreshing all data. To completely delete all SMW data, the setup script SMW_setup.php is used with parameter --delete:

php SMW_setup.php --delete

After this, proceed as if re-installing SMW anew by first running php SMW_setup.php again, and then triggering the repair of all data using one of the above methods. The refresh script SMW_refreshData.php can be also used with parameter -f to delete and recreate all data in one step. In this case, it is suggested to first rebuild the records for all properties and types, and to process the remaining data afterwards. So one would run:

php SMW_refreshData.php -ftpv
php SMW_refreshData.php -v

Note that of course only the first run uses -f. On large wikis, the parameters -s and -e can again be used as explained in the previous section.

Not sure if this is the kind of level you are after but this is what I wrote
up for use in my organisation if we need to perform a complete disaster
recovery of our wiki. This has been tested numerous times for both recovery
on the same server, as well as migrating to another server. I haven't tried
between OS though but don't see there would be any issues with that.

Before doing this, Apache2 needs to be configured in the same manner (ie
same directory root etc), correct php version installed and compiled, etc.

A couple of things: wikidb.servername.$DAY is just a gzipped mysql dump of
the database. wikifiles.$DAY.tbz is simply a tar of the entire directory
structure. I have a cron job run daily to backup both.

Create Database
Mysql –u root –p
Create database wikidb;
Exit
Restore Database files
Cd /<backup location>
Gunzip wikidb.servername.$DAY.gz
Mysql –u root –p wikidb < wikidb.servername.$DAY

Ensure database restored
mysql -u root -p wikidb
show tables;
<list of tables (about 35 should appear).

Create Wiki User account in MYSQL
Mysql –u root -p
create user 'wikiuser'@'localhost' IDENTIFIED BY 'password to be used:
IMPORTANT make sure this is also the same as in the LocalSettings.php
file!';
Grant privileges to wikiuser on wikidb database
Mysql –u root –p
GRANT ALL ON wikidb.* TO wikiuser at localhost IDENTIFIED BY 'password to be
used';
Flush privileges;

Restore wiki config files and images
Cd /
Tar –xvjf /<backup location>/wikifiles.$DAY.tbz
Complete restore process complete – to make sure, perform test plan again

Potential things that ** may ** be required are:
/<wiki install>/maintenance/php5 rebuildall.php
Double double check the correct database, username, password are used in the
/<wiki install>/LocalSettings.php file
Make sure apache is set up correctly, and the wiki location set
appropriately in the LocalSettings.php file
