Windows 7: Win 7 backup fails to complete

4% is pretty small for a system drive shadow copy. That's what Winsxs is and allows for system restore points. That's not part of system reserved. System reserved area has it's own shadow file(s) to allow repair of the boot sector and some system settings.

You can increase the size of the shadow copy file by changing the system properties. You also can turn it off but you better have another method to restore your system unless you enjoy reloading the OS on every problem.

Added: You don't need a shadow copy on a backup disk. That what the whole disk is for.

I know I made (a reliable?) backup with True Image, but I'd like to resolve this if I can.

Are you saying that MS Backup failed because the 4% shadowfile allocation is too small and I should increase it - to what? 've done a dummy run and get these.

Why is it showing (c(missing)? I've named the system reserved partition L: but that's not showing up here.

Run WinDirStat for the little partition. Maybe that gives you a clue. http://windirstat.info/

To see if it's the USN Journal taking up your space, per a Microsoft chap:

Assume that your System Reserved partition is F:
1. Lauch cmd -> Run as Administrator
2. Fsutil usn queryjournal F:
This will output the settings of the USN journal.
3. Check the Maximum size field. This gives you the space used (in bytes in hex) by the USN journal on the volume.
4. Open calc and set in hex mode and paste the value.
5. Change mode to decimal and divide by 1048576 (ie. 1024 * 1024) to get the number of MB.
6. If you see this to be anything of the order of 30 MB, backup will fail owing to lack of space.
And to answer your question, also per Microsoft chaps:

1. Choose where you want to have your system volume. Few things you need to keep in mind:
a. System volume can only be created on a primary partition of MBR disk.
b. If system volume & boot volume are together, then BitLocker feature cannot be used to encrypt volumes on your machine.
2. Suggest creating a new volume (say F: ) on the same disk that contains the boot partition of size of about 490 MB (be careful to keep it less than 500 MB).
3. Assuming Windows 7 is installed on C: on your machine. From an elevated command-prompt run: bcdboot.exe /s C:\Windows /s F:.
4. From elevated command-prompt run: DISKPART
5. From the disk part command-prompt:
DISKPART> select volume F
DISKPART> active


Now you can reboot your machine and F: will become the system volume. You can undo this by repeating the same steps using the original system volume (you have to assign drive-letter to it) to revert to your previous configuration.

Stay away from the "System Reserved" partition. It shouldn't have a drive letter and it should not be on your backup disk unless you're creating an image. The only place it should appear is on your boot disk. Don't confuse System Protection space (Winsxs) with the System Reserved area. They have nothing to do with each other. If you're using imaging software to create backups then don't use Windows Backup. You can't use both to the same disk. Choose one or the other.

What partition are you "missing" 80MB? If it's the system reserved area, I've already shown that there are more hidden files in the partition than you can see with Windows Explorer. As such, don't touch it. It has it's own "backup". See post #7.

I agree completely about not touching the System Reserved partition. The reason I gave it a drive letter was to see what was filling it up, but I couldn't see it anyway. How did you get the listing in your earlier post?

I managed to make a backup with Acronics so I should be happy with it, but I'm concerned that the almost full system reserved will give me trouble down the line as it did with MS Backup and with Macrium Select as well. I tried to expand it with Disk Management but couldn't. See post 21. I've checked the old c: disk that I cloned to the ssd and the system reserved was only 30% used, with 70MB free. The only new stuff is the Samsung Magician software for the ssd, Macrium Reflect and the video editor. How can I find out if any of these are filling up the reserved area other than by unistalling them, which never takes everything out anyway. Maybe I should start from scratch again and check at every step.

I'm a bit confused with your comments about not creating an image and backup on the same disk. Doesn't the first backup need a system image to restore from? The default MS Backup setting is "Files in selected folders and system image". I've been lucky enough to never have lost a system disk and have to do a complete restore. I always assumed you had to boot up from a system recovery disk and restore from a backup that had the system image as well as user data. Have I got it wrong?

Thanks for your comments.

From what I read, I believe he means that if you're using Acronis there's no reason to use Windows Backup as well. They're doing the same thing, at any rate.

I can't speak for Acronis, but the process of restoring from a Windows image backup is booting from the recovery disk and finding your .vhd file on the backup HD. The system does the rest and your computer should be right back to what it was like when you took the image. The user data is on the image. Everything on the disk you imaged is. It's basically a compressed clone.

For instance, Windows .vhd image files actually let you "mount" the image -- which shows you a virtual representation of your exact drive at the time the image was taken. I can mount a backup image I've done and use Explorer the same way I do with my actual C: looking through user profiles, Program Files, etc. (of course, there won't be any new files / changes that happened after I made the image).

So all you need is the image. The file backups just give you another way to quickly restore specific files -- they're not needed to complete a restore from image (if that's what you were getting at). For instance, say I delete a file and want to restore it -- I could use file backups to grab the file from when I backed up and bring it back.

At any rate, if you're worried about your System Reserved partition read through the thread linked on the bottom of post 24 -- I quoted the Microsoft Employees solution, but it's always better to read these things for yourself. Second post on the link.

@absc
I can't see your disk management report/screenshot. If your system reserved partition is filling beyond 50% then Windows imaging is likely to fail. This is what you could try
Backup Error 0x81000019 - Fix
Windows imaging has worked fine for me but it is a bit more restrictive and some just don't like it. I recommend using 2 imaging software packages and personally use Windows inbuilt imaging and (free) Macrium Reflect.

@ ABSC - I made a drawing to help you understand the difference between a Disk Image, a System Image and a Windows Backup and how they compare to one another when used for a backup and restore process. Included in the drawing are Windows' own recovery files. How the backup "images" are handled vary by the designer of the backup software but when discussing a "Disk Image", it commonly refers to an exact copy the entire disk regardless of any partitions.
