How do I restore from a backup?

I want to restore my wiki from an older backup. What I did is to deleted the queue and l10n_cache database files and replaced <my_wiki>.sqlite with the backup. However, after I did these and trying to visit the wiki, those two database files I deleted wasn't recreated as I expected and the wiki page prompts something like this:

#0 /var/www/html/includes/libs/rdbms/database/DatabaseSqlite.php(142): Wikimedia\Rdbms\DatabaseSqlite->open(false, false, false, 'my_wiki_l10n_ca...', NULL, '')
#1 /var/www/html/includes/libs/rdbms/database/Database.php(350): Wikimedia\Rdbms\DatabaseSqlite->doInitConnection()

#23 /var/www/html/includes/MediaWiki.php(515): MediaWiki->main()
#24 /var/www/html/index.php(42): MediaWiki->run()
#25 {main}


It looks like the error is about missing database/table. How can I resolve it? BTW here's my database related config in LocalSettings.php:


# SQLite-specific settings
$wgSQLiteDataDir = "/var/www/data";
$wgObjectCaches[CACHE_DB] = [
  'class' => SqlBagOStuff::class,
  'loggroup' => 'SQLBagOStuff',
  'server' => [
    'type' => 'sqlite',
    'dbname' => 'wikicache',
    'tablePrefix' => '',
    'variables' => [ 'synchronous' => 'NORMAL' ],
    'dbDirectory' => $wgSQLiteDataDir,
    'trxMode' => 'IMMEDIATE',
    'flags' => 0
  ]
];
$wgLocalisationCacheConf['storeServer'] = [
  'type' => 'sqlite',
  'dbname' => "{$wgDBname}_l10n_cache",
  'tablePrefix' => '',
  'variables' => [ 'synchronous' => 'NORMAL' ],
  'dbDirectory' => $wgSQLiteDataDir,
  'trxMode' => 'IMMEDIATE',
  'flags' => 0
];
$wgJobTypeConf['default'] = [
  'class' => 'JobQueueDB',
  'claimTTL' => 3600,
  'server' => [
    'type' => 'sqlite',
    'dbname' => "{$wgDBname}_jobqueue",
    'tablePrefix' => '',
    'dbDirectory' => $wgSQLiteDataDir,
    'trxMode' => 'IMMEDIATE',
    'flags' => 0
  ]
];

Reinstall MediaWiki, then replace the files you have a backup for. You can reinstall by moving LocalSettings.php away and later putting it back.
