    I have Windows Vista Home Premium, and have been using the Backup tools that
    come with Vista. I've been performing backups of my C drive to an external
    harddrive (M).

    For the most part the backup have been working, and I have tested recovering
    files. However today I got an error that I cannot figure out:

    The last file backup did not complete succesfully. Details:
    "There is not enough space on your Windows disk to prepare for backing up
    your files. At least 400MB of free space is required to continue.

    I have over 183GB for free space on C. And over 297GB of free space on M.
    I'm not sure where it can't find 400MB of space in all these free GBs. Any

    I have the same problem, and I see several others have reported it too. I've
    found no help anywhere.

    Thanks for your reply. My guess is it's some sort of bug?
    Because the next day it ran fine with no error mesages.

    So I'm guessing the backups are okay, but I'd have a lot more confidence in
    a backup system if it didn't give off error messages like this from time to

  4. Hi Laura & jmp,

    Is that error a one-time issue, or has it been showing up constantly even
    though there's enough space on your external HDD?

    Christine and others...

    I just started getting this same error.. I deleted the old backup and
    started from scratch and go it.. now several times... sometimes it took
    longer than others until it stopped..

    I dont know whats going on as everything was fine... sould an MS update have
    botched this up? Because all was fine until recent. I did run disk cleanup
    but doubt that would have to do with it as I ran this before.

    SOmeone please help with this

    I am running Ultimate 32 bit.

    Is the backup destination a FAT32 external hard drive?

  8. Hi Mike,

    Can you send me all the etl files under C:\Windows\Logs\WindowsBackup?
    (remove "online" from my email address)

    Also, can you send me the output of typing this command on an elevated
    command prompt? (Start Menu->type "cmd"->right click->select "run as
    vsssadmin list shadowstorage

    It's nice of you to offer personalized help but it would be even more
    helpful if it was done through this newsgroup so others can benefit as well.

    The etl files need to be examined by someone familiar with their meaning,
    and attachments are generally discouraged in newsgroups. Both good reasons
    to have them sent via email. Hopefully Christine will respond to the group
    with her findings for everyone's benefit.

    Is there any traction on this issue?

    I had a backup set run fine a few times and then fail with this
    error. It was one of the reasons I was looking forward to SP1. No
    joy, same error.

    I have 46GB free on the C:\ and over 400GB free on teh bcakup drive.

    The error message says that it needs at least 400 MB free space to
    continue (but it does not say where!)

    I just reformatted my drive and reinstalled everything after updating to SP1...

    STILL getting this error ahbout 400 MB free. I can keep restarting the
    backup but this error keeps on coming.

    I too have this issue constantly, lots of search results for this problem but
    no solutions anywhere - come on Microsoft let's get this resolved, I didn't
    pay good money for Vista Ultimate to get broken bits...

  16. Hi Jason, we haven't been able to pin point the issue from some of the
    previous logs sent by other customers. It'd be great if you could share you
    trace files as well. (C:\Windows\Logs\WindowsBackup)

    Have emailed those, but of the 7 files sent, 5 of them are around 10mb and
    have been rejected by your mailserver, is there another way to send them?

  20. You could try one of those online file transfer sites, such as or
