Site backup through Central Administration site

You can take the site collection back up through central administration site apart from using the BackUp-SPSite and Restore-SPSite PS command. The advantage of this approach is getting the status report while your site being backed up by the timer services.

 You can prefer this backup approach, if you are continuously taking the back up of huge site because It lets the administrator to have his/her network shared location which can be attached the high end storage medium (SAN). Before this, you need to create the shared folder location and set the access permission (Read and Write) for it.

It support the granular backup approach

You can also restrict the user permission over this folder by selecting the specific user or group.

 I have the small site collection at my machine and backed up through this approach.One should aware of the advantages and disadvantage by comparing the PS Commands BackUp and Restore. Once you backed up the site collection, you need to verify its integrity this where lack this approach. BackUp-SPSite has the parameter UseSQLSnapshot.

SharePoint Online SystemUpdate Vs Item Update

In CSOM / REST Api for SharePoint Online, We have new method for List Item called "SystemUpdate".

This is an attempt to bring the same functionalities of Server Side Object Model (SSOM) into SharePoint Online also.

This method is very useful, if you wanted to retain the Modified By and Modified Date on your SharePoint list for Auditing purpose when you migrate to SharePoint Online.

Its appropriate to understand the difference but List Item's Update method and System Update method.

If you want to update the fields Modified, Modified by then you can explicitly assign the new values to its field or you can also ignore when you call the method Item.Update().

If you wish to retain the Modified and Modified By column but wanted to update the rest of the fields, then you should use the Item's SystemUpdate method.

            {
                securePassword.AppendChar(c);
            }

            var onlineCredentials = new SharePointOnlineCredentials("murugesan@codethinker.onmicrosoft.com", securePassword);
            var context = new ClientContext("https://codethinker.sharepoint.com/");
            context.Credentials = onlineCredentials;
            List oList = context.Web.Lists.GetByTitle("Friends");
            context.ExecuteQuery();
            ListItem item = oList.GetItemById(35);
            item["xm2s"] = "+91-xxx-7887-xxxx";
