If all you want is to create a backup of some file you can do:public class Foo
    public static void main(String[] args) {
        Foo f = new Foo();
        f.createBackup("something.xls");
    public void createBackup(String inFile) {
        FileInputStream in = null;
        FileOutputStream out = null;
        try {
            in = new FileInputStream(inFile);
            out = new FileOutputStream(inFile + ".bak");
            int read;
            while ((read = in.read()) > -1) {
                out.write(read);
            out.flush();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
}
