Programmatically Creating Site Backup in SharePoint

In the previous article, we have discussed about creating and restoring the SharePoint site using stsadm command.

In this article, we will see how to take the backup of the site using SharePoint Object Model.The below is the code that will create the backup of the site and log the information in a log file.

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;

namespace SiteBackUp
{
    public class SiteBackup
    {
        static void Main(string[] args)
        {
         siteBackup("http://servername:portnumber","SharePointSiteBackup");   
        }
        public static void siteBackup(string siteURL,string fileName)
        {
            try 
            {
                SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                    using(SPSite objSite=new SPSite(siteURL))
                    {
                        using(SPWeb objWeb=objSite.OpenWeb())
                        {
                            bool currentSiteStatus=objSite.AllowUnsafeUpdates;
                            objSite.AllowUnsafeUpdates=true;
                            bool currentWebStatus=objWeb.AllowUnsafeUpdates;
                            objWeb.AllowUnsafeUpdates=true;
                            string comment = objWeb.Title+"- Creating Backup is completed";
                            SPSiteCollection siteCollection=objSite.WebApplication.Sites;
                            objSite.ReadOnly=true;
                            string time=DateTime.Now.ToString("dd-MM-yyyy");
                            string backupName= "D:\\SiteBackup\\Backup" + fileName+"_"+time+".bak";
                            siteCollection.Backup(siteURL,backupName,false);
                            objSite.AllowUnsafeUpdates=currentSiteStatus;
                            objWeb.AllowUnsafeUpdates=currentWebStatus;
                            if(objSite.ReadOnly==true)
                            {
                               objSite.ReadOnly=false;
                               siteBackupLog(comment);
                            }                        
                         }
                    }
                });
            }
            catch (Exception ex)
            {
                SPSite site = new SPSite(siteURL);
                if (site.ReadOnly == true)
                    site.ReadOnly = false;
                siteBackupLog(ex.Message);
            }
        }
        public static void siteBackupLog(string message)
        {
            string PathName = "C:\\SiteBackup logs\\";
            PathName = PathName + "Backuplog-" + DateTime.Now.ToString("dd-MM-yyyy") + ".log";
            StreamWriter sw = new StreamWriter(PathName, true);
            sw.WriteLine(message + " - " + DateTime.Now);
            sw.Flush();
            sw.Close();
        }
    }
}

Hence, we can automate creating backup of the SharePoint site using code. Also, the whole code created in visual studio can be downloaded here.

Happy Coding!
