    reinstalling Win 8.1 and OneDrive data from local backup


    I have a laptop with Windows 8.1 installed. A lot of my files are synchronized to OneDrive. I want to reformat and reinstall Windows but I want to restore all the OneDrive files from a local backup instead of redownloading them all from the OneDrive files on the Internet. Does anyone know if there would be an issue with copying all the files back into the OneDrive folder after reformatting but before resynchronizing the files with OneDrive online? I was hoping OneDrive would notice that the files are the same as the ones online and would not try to upload them again. However, I ran into an issue with the past where I tried to manually copy files back to the OneDrive folder and then it started uploading them all to the cloud again but this time with the PC name in the folder name. Apparently it thought the files were modified both online and on the PC. It was a mess. Has anyone else tried this before?

    I've been wondering the same recently. I have 300GB or so in OneDrive that I don't want to have to download every time i reformat. Hopefully someone has something on this.

    Well, here is what Microsoft said when I talked to someone on their online chat website. I ended up taking their suggestion and let it download from OneDrive instead of restoring from a local backup. My computer has been running for at least 1.5 days and it's only at 40% download completion. At this rate hopefully it'll be done by Saturday or Sunday. LOL

    Dear Jeff,
    Hello Jeff. This is Mark, one of the answer tech from Microsoft. The one that you've talked about the backing up of OneDrive files.
    As you mentioned that you already back up the OneDrive folder but you're just thinking not to redownload it after reinstall the Windows 8.1.
    What I can recommend you is to just logged in your OneDrive account then the files from OneDrive cloud will automatically sync on your computer. I know that it will take a while but that's is the best way. So that, you may not experience any issue just like what you said that it messed up.
    If you have any questions or any concern, just feel free to contact us back and we will be happy to assist you.

    First off I don't use one drive. but I have an idea that might work. Maybe a sync program like Good Sync could save the situation I say this as I use it and it reconizes all the files and folder on both drives and then would only restore the files and folders that are missing hopefully at the same time marking the files as synced to One Drive at the same time?

    This thread, to me show that One Drive, is not actually ready for prime time. Cloud Back up programs such as Carbonite do this automatically

    Yeah, that's my thinking as well. Re-downloading hundreds of Gigabytes when you have local copies is ludicrous.

    Maybe they can get away with it with users who only have a few Gigabytes, but when it's hundreds of Gigabytes or more, OneDrive really needs to be bulletproof and extremely well thought out from every single angle. Half measures isn't going to cut it.

    I listened to one of the speeches at Ignite about OneDrive Sync Capabilities and although it was targeted towards OneDrive for Business, the impression I got was that they hadn't really thought the OneDrive sync engine through at all from an engineering perspective. In the latter part of the video, the speaker was receiving some good questions from the audience, but if you ignored his charisma and listened to his actual words, he was struggling and there were a lot of unanswered questions where he evaded them politician style. They've got a way to go yet I think and I really do hope that they go back through those questions that were asked and take them on board with their unified sync engine.

    I have found this the case, any changes seen to the files, and the whole file is re uploaded

    If you are planning on upgrading to win 10 when it comes out, try and use just the placeholders features for 8.1 after a re install and only downloading/making local what you need
    When you upgrade to win 10, it will ask you to re download them all again (as onedrive has changed in 10)

    That was my experience in upgrading 8 to 10, it wants you to delete all local copies and re download from onedrive

    I was probably going to reformat when 10 comes out anyway. However, if you have to redownload all the OneDrive files when upgrading over top of 8 that really sucks.

    I use File History to another drive and it saves all changes to OneDrive too. In my case it saves them to F:\FileHistory\Clifford\TOWER-PC (4)\Data\C\Users\Clifford\OneDrive
    Click image for larger version
    All you then have to do before formatting is manually run File History, and then restore all your files(not just OneDrive) from it. The tools are there without 3rd party software.
