    Storage Space and Space Pooling in x32Win10ProV20H2


    I used to edit material on an external HDD which I would back up monthly. When that drive failed, I realised that I should have been backing up the edits between month's ends. Then I saw that Storage Spaces in Settings;Storage, promised to 'save files to 2 or more drives' and that seemed to be what I needed. When I started the process of 'creating a new pool and storage space' I saw a warning that Windows would delete all files off the HDDs in the pool. I did not want to lose what was on the original ext HDD which I was editing, so the Storage Spaces mechanism no longer seemed suitable - unless I misunderstood the warning. Can someone clarify for me ?
    The external HDD failure consisted of it no longer showing up in THIS PC and Disk Management in two different PCs.

    Storage Spaces seems not much used, and some of those who have used it have had some bad experiences.

    As your experience suggests, maintaining the integrity of your disks- continuous monitoring for degradation- is vital.

    MS has broken Storage Spaces from time to time, in particular when upgrading:

    A couple of users have found moving a storage space from one PC to another didn't work.

    I am willing to try Storage Spaces and abandon it if not 'as desired'. My concern in making the post is specifically : does Windows REALLY wipe everything on both pooled HDDs before it does any double saving ?

    Thank you very much for your reply.


    You don't show a screenshot, so I am uncertain to which part of the process of creating a storage space you are referring. I pointed you to the tutorials. I now provide you with a screenshot of part of one of them, which shows a warning which might be what you are referring to.

    Your question about double storage / redundancy appears to relate to the normal operation of storage spaces once configured, so seems obscure.

    My impression is that few here have used storage spaces.

    Note too the warning in

    Your screen shot shows two unformatted drives - well they can not have any data that Windows could wipe - then there is a third formatted drive with a warning above it that Windows will wipe it. That is the warning which concerns me.

    My scenario is that I have an external drive with data - I edit some of that data and save the changes to that external drive. Because of my bad experience I want to 'automatically' save those changes to another drive, which would start off empty, but as the month progresses, would accumulate ever more saved edits. Can I expect POOLED SPACES to do that automatic double-saving for me [to the original external, as well as to an initially-blank auxiliary HDD] WITHOUT loss of data from either HDD ?

    "Your question about double storage / redundancy appears to relate to the normal operation of storage spaces once configured, so seems obscure." If my question is obscure, your comment about it leaves me uncomprehending. Are you saying that Storage Spaces does exactly what I need ? In which case, how to interpret Window's warning about wiping data ?

    Again, thank you very much for your reply.

    I would again ask for the screenshot so you can show exactly what you mean to be sure.

    I would again point you to the tutorial:

    Create a New Pool and Storage Space in Windows 10

    Is it the creation of a storage space and the deletion of existing data that concerns you? See then this note in the tutorial to which I have pointed you:

    4
    Click/tap on Yes if prompted by UAC.
    5
    Select (check) the disks you want to add to the new storage space to create a storage pool, and then select Create pool. (see screenshot below)

    Windows will permanently delete all partitions and files on selected formatted drives (disks).
    Be sure to back up anything you do not want to lose to another disk first.
    I.e.

    To create a storage pool, use drives you expect and are happy to be wiped.
    Therefore don't include drives containing your data when doing so.

    "Don't include drives with data" - so it is NOT suitable for the purpose that I have TWICE described in detail.....

    That means- you create your storage spaces with OTHER drives, then transfer data from the drive to the new storage space.

    For example.

    And again, thank you for your reply. Still no screenshot. Good luck with this.

    I will try to explain my situation again and beg you to tell me if Storage Spaces is applicable to my need ASSUMING that Storage Spaces works as intended.

    I OBVIOUSLY have a system drive - call it C; I have an external drive (call it D) that I take data from to edit in C. Once the editing is done, I want to transfer it back to D; but I also want to do a backup to another drive (call it E) which starts off empty, but accumulates edits throughout the month. Then at month's end, I clone D - and no longer need the backups on E. Can I use Storage spaces to automatically save to E as well as D, without losing the original data on D - or the accumulating edits on E ?

    I'm sorry you so desperately need a screenshot - but I have no idea what to show you in it.

    I am fairly sure the answer is 'yes'. But once you set up SS, you don't get to control what gets stored on E, because SS is in charge. You just keep using D as before, and let SS worry about E.

    That said, what I think is causing the confusion is the question of what happens when you set up SS: it is unambiguous that it will clear any existing data on the pooled drives. So you must be happy to initially lose everything on D & E. The way to get over this would be copy back the data from a third disc (your clone) after setting up SS. But I would say not by cloning #3 to D (or E) as that would almost certainly confuse SS - it would have to be a normal file->file copy.

    Does that help? Martin

    PS I would probably deal with your situation by imaging from D to E daily, although that would need incremental images to avoid wasting space. Or perhaps I would just do a double copy from C to both D & E. In all 3 cases you are vulnerable to the loss of nearly a month's work if the PC blows up badly enough.

    PPS If you set up SS, and call the pooled discs 'D', you won't actually see an 'E'.
