Sharepoint 2013 Online Site Collection Backup-Restore using CSOM

Question

I have created one site collection on SharePoint Online.

Now I want to make another site collection with the same content.

So can anyone explain me how to go about backup and restore of site collection in SharePoint Online (Office 365)? Using CSOM

Answer 1

Save your site as template manually. Then find the template guid id.

Now create your site using CSOM. See more here

internal void CreateSite(String targetUrl, String title, String owner, String siteTemplate)
{
    var ctx = new ClientContextWrapper(targetUrl);
    var tenant = new Tenant(ctx);

    //Create new site
    var newsite = new SiteCreationProperties()
    {
        Url = targetUrl,
        Owner = owner,
        Template = siteTemplate,
        Title = title,
        StorageMaximumLevel = 1000,
        StorageWarningLevel = 500,
        TimeZoneId = 7,
        UserCodeMaximumLevel = 7,
        UserCodeWarningLevel = 1,
    };

    var spoOperation = tenant.CreateSite(newsite);

    ctx.Load(spoOperation);
    ctx.ExecuteQuery();

    while (!spoOperation.IsComplete)
    {
        Thread.Sleep(2000);
        ctx.Load(spoOperation);
        ctx.ExecuteQuery();
        Console.WriteLine("Site creation status: " + (spoOperation.IsComplete ? "waiting" : "complete"));
    }
}

Place your custom template's guid in siteTemplate
