Using Backup/Restore feature

Feb 9, 2011 at 2:50 AM

This is my first attempt to do a Online backup/restore.

I've made a DomainService that receives a "WebFile" class, containing info and the bytes of a stream created by silverlight client to create some kind of CSV file on webserver

public class WebFile

        public string FileName { get; set; }
        public int UserId { get; set; }
        public byte[] FileContent { get; set; }
        public bool IsCompressed { get; set; }



At Silverlight Client, the method I use to create an instance of a webfile class is:


static void SaveTable()
            using (var memoryStream = new MemoryStream())
                using (var streamWriter = new StreamWriter(memoryStream))
                    foreach (var tableKey in Global.LocalDbService.Database.Query<TabelaPreco, Guid>())
                        var tabelaPreco = tableKey.LazyValue.Value;
                        streamWriter.Write((int)tabelaPreco.EntityStatus + ";");
                        streamWriter.Write(tabelaPreco.Id + ";");
                        streamWriter.Write(tabelaPreco.EstacionamentoId + ";");
                        streamWriter.Write(tabelaPreco.DataCadastro + ";");
                    var file = new WebFile
                                       UserId = Global.UsuarioRegistradoId,
                                       IsCompressed = false,
                                       FileName = "01_TabelasPrecos_" + DateTime.Now.Ticks,
                                       FileContent = memoryStream.ToArray()

            RemoteSaveDomainContext.SubmitChanges(submit =>
                                                          if (submit.HasError)
                                                      }, null);


This is the method of the DomainService on the server project:

public void InsertFile(WebFile file)

            if (ProcessFile(FileHandler.HandleFile(file)) >= 0)
                //delete file after processing

the ProcessFile method writes the contents of the Webfile instance to the disk, and then iterate over the CSV, doing inserts/updates/deletes.

That's a boring work to do.


I would like to see if someone is using the new backup/restore feateure of sterling current version, and examples.
