Answer 1

If you want to backup into a file, the content of your H2 instance as a SQL script, you can directly use SCRIPT TO 'path/to/my/file.sql'.

try (Connection con = ...;
     Statement stmt = conn.createStatement()) {
    stmt.executeQuery(String.format("SCRIPT TO '%s'", sqlFilePath));
}

If you want to backup it as a ZIP archive, you can use BACKUP TO 'path/to/my/file.zip'.

try (Connection con = ...;
     Statement stmt = conn.createStatement()) {
    stmt.executeQuery(String.format("BACKUP TO '%s'", zipFilePath));
}
