WireDatabaseBackup class

ProcessWire Database Backup and Restore

// Get an instance of WireDatabaseBackup
$backup = $database->backups();

This class intentionally does not have any external dependencies (other than PDO)so that it can be included by outside tools for restoring/exporting, with the main example of that being the ProcessWire installer.

The recommended way to access these backup methods is via the $database API variable method $database->backups(), which returns a WireDatabaseBackup instance, however you can also initialize the class manually if you prefer, like this:

// determine where backups will go (should NOT be web accessible)
$backupPath = $config->paths->assets . 'backups/';

// create a new WireDatabaseBackup instance
$backup = new WireDatabaseBackup($backupPath);

// Option 1: set the already-connected DB connection
$backup->setDatabase($this->database);

// Option 2: OR provide a Config object that contains the DB connection info
$backup->setDatabaseConfig($this->config);

Backup the database

$file = $backup->backup();
if($file) {
  echo "Backed up to: $file";
} else {
  echo "Backup failed: " . implode("<br>", $backup->errors());
}

Restore a database

$success = $backup->restore($file);
if($success) {
  echo "Restored database from file: $file";
} else {
  echo "Restore failed: " . implode("<br>", $backup->errors());
}
