How can I do daily backups for my VisualSVN Repos? [duplicate]

It's a bunch of files, like any other bunch of files. Use whatever method you use to backup the rest of the system. As this is on a server I would have thought it would already be included in the regular backup scheme.

If you're using half-decent backup software, even Windows own NT Backup, it should be using the Volume Shadow Copy service, which will take care of open file issues, if any.

Just copying the repo files is a bad idea:

...unless you temporarily disable all other access to your repository, simply doing a recursive directory copy runs the risk of generating a faulty backup.

You should use the The svnadmin hotcopy command.

Repository Maintenance > Repository Backup

You could script this and run it as a scheduled task.

I do both dump and hotcopy. Put them in a batch file and create a task with Task Scheduler to run it daily. Here is my sample batch file

!backing up credentials
copy H:\Repositories\authz G:\Repo-Backups\7-22-2013\backup
copy H:\Repositories\authz-windows G:\Repo-Backups\7-22-2013\backup
copy H:\Repositories\htpasswd G:\Repo-Backups\7-22-2013\backup

!full dump
svnadmin dump H:\Repositories\Proj1 > G:\Repo-Backups\7-22-2013\dump\Proj1
svnadmin dump H:\Repositories\Proj2 > G:\Repo-Backups\7-22-2013\dump\Proj2 

!hard copy
svnadmin hotcopy H:\Repositories\Proj1 G:\Repo-Backups\7-22-2013\backup\Proj1
svnadmin hotcopy H:\Repositories\Proj2 G:\Repo-Backups\7-22-2013\backup\Proj2 

If you have several repositories (projects) to backup and they change frequently it would be easier to have a little program create the above batch file for you. Here is what I've written for this purpose:

    public static void CreateBackupScript(string srcFolder, string desFolder, bool fullDump)
        { 
if (string.IsNullOrEmpty(srcFolder) || string.IsNullOrEmpty(desFolder))
            return;

        var dateString = DateTime.Now.ToShortDateString().Replace('/', '-');
        var destination = System.IO.Path.Combine(desFolder, dateString, "backup");

        if (!Directory.Exists(destination))
            Directory.CreateDirectory(destination);

        var source = srcFolder + "\\";
        var outputScript = "backup.cmd";
        using (StreamWriter sw = new StreamWriter(outputScript))
        {
            sw.WriteLine("!backing up credentials");
            sw.WriteLine("copy {0}authz {1}", source, destination);
            sw.WriteLine("copy {0}authz-windows {1}", source, destination);
            sw.WriteLine("copy {0}htpasswd {1}", source, destination);

            // dump
            if (fullDump == true)
            {
                sw.WriteLine("!full dump");

                var dumpFolder = System.IO.Path.Combine(desFolder, dateString, "dump");

                if (!Directory.Exists(dumpFolder))
                    Directory.CreateDirectory(dumpFolder);

                foreach (var dir in new DirectoryInfo(source).GetDirectories("*.*", SearchOption.TopDirectoryOnly))
                {
                    sw.WriteLine(@"svnadmin dump {0} > {1}\{2}", dir.FullName, dumpFolder, dir.Name);
                }
            }

            //hot copy
            sw.WriteLine("!hard copy");
            foreach (var dir in new DirectoryInfo(source).GetDirectories("*.*", SearchOption.TopDirectoryOnly))
            {
                sw.WriteLine(@"svnadmin hotcopy {0} {1}\{2}", dir.FullName, destination, dir.Name);
            }
        }
    }
