Question

I am developing one c# .NET application.

I am using database of Microsoft Access(OLEDB).

I want to take back up of database time to time (Programatically).

(Or As i can create .bak file in sqlserver2008 r2)

What should i do?

Answer 1

An Access database is usually a single file.
To do a programmatic backup you can simply use a

File.Copy(sourceDbName, destDbName, true);

Of course you can add a simple routine that takes your input database, zip and store it, in your backup directory, optionally passing a password, like this:

using Ionic.Zip;
......

private void BackupToZip(string sourceDBName, string destZipFile, string password)
{
    using (ZipFile zip = new ZipFile(destZipFile))
    {
        if (bkpPass.Length > 0) zip.Password = password;
        ZipEntry e = zip.UpdateFile(sourceDbName, string.Empty);
        e.Comment = "Working copy stored in date: " + DateTime.Today.ToShortDateString();
        zip.Comment = "This zip archive has been created by ......";
        zip.Save();
    }
}

this snippet of code requires the DotNetZip Library
