Deploying changed files only (web application)?

Hi, is there a way to deploy only changed files of a website, and not all of them? Maybe this already is done automatically?
Often in our case the .net website only needs the new dll to be updated server side. Not the hundred small graphic, js-files etc that of course becomes part of the default project artifact package, since it's a package of the entire site, not just the changes since last time.
Does the agent or other deployment options take this in account server side?, so that only updated files are actually updated, and then usually just the web application dll?

    Well, Web Deploy is what you need. AppVeyor Deployment Agent synchronizes website contents using Web Deploy, so even it always downloads the entire application package it does not replace the entire app, but deploys changes only. You can see that in deployment log.

    Ok. I'm not really sure what you're saying. What I gather is that the deployment agent shouldn't update all files, and neither should a web deploy deploy, is that correct?
    At the moment I'm trying out the agent with a web deploy artifact. I pushed a code change. Waited. Afterwards I checked the console log at the Deployment tab on the project pager. Console seems to tell me all files in the project are updated. (Total changes: 3115 (0 added, 0 deleted, 3115 updated,....)). Even though the majority, practically none , should have. Guess I've must have forgotten something or gotten something backwards. What more do I need to do to make sure only updating files that are changed? Reading wrong log? Do I need to switch away from the agent, or just tweak/install something on the server to make the web deploy work if that's what the agent can use?

    Yeah, that's strange. Web Deploy should do updates only. I will give it another try here to see if there are any issues. Will let you know about results.

    Found something? Tried a couple of more times with same result as earlier.
    All files reported as updated. It's an old version of web application,
    built in vb.net. How does it compare files/know which ones to update?
    Agent/Webdeploy use some kind of hash solution? If it uses agent uses web
    deploy in the background and not just knows how to unpack the files in web
    deploy zip, should we make sure web deploy is installed on server and not
    just the agent and IIS?

    Hi Emanuel,

    You know, you are right. It always syncs all files and it could be reproduced for both Web Deploy and Agent environments.

    Apparently, Web Deploy uses timestamps (in addition to checksums and attrs) to decide whether the file was change and every build packages files with updated timestamps as Git does not store this metainformation.

    However, it seems there is "cure" to that. I will try something and let you know about results.

    Glad there's a possible cure!
    Keeping my fingers crossed.
    Thanks! :)

    OK, Web Deploy now uses checksums only for comparing files. Worked like a charm on our test projects (see attached screenshot).

    Update Deployment Agent from here: http://www.appveyor.com/downloads/AppveyorDeploymentAgent.msi

    Let me know if you have any questions.
