Windows 7: Backup Error 0x81000019 - Fix

   Information

This tutorial will help show you some ways to deal with the backup error 0x81000019 which prevents you from creating a Windows System Image.

USN journal files can accumulate in the system reserved partition. If you don't have 40-50MB of free space then shadow storage copy in this partition can't occur and you get 0x81000019 errors when making a system image.

OPTION ONE

Try This First

1) If System Reserved has less than 50MB of free space then continue or else go to Option Two.
2) Assign a letter to system reserved with Disk Management eg F:
Drive Letter - Add, Change, or Remove in Windows 7
3) From a command prompt run
> fsutil usn queryjournal F:
you will probably see journal files
4) clear and disable USN journal file from system reserved by
> fsutil usn deletejournal /N/D F:
5) Using Disk management, remove the partition letter F:
Drive Letter - Add, Change, or Remove in Windows 7

OPTION TWO

Try This Second if OPTION ONE Doesn't Help

1) Increasing the size of system reserved.

1.1) Boot the Partition Wizard disk and highlight your OS partition to the right of System Reserved (let's call it C: ).

1.2) Drag the left handle of C: to the right by around 100MB to create a region of unallocated space between System Reserved and c:. Note: you may drag a little by hand then go down and enter more precise numbers in the field shown below.

1.3) Highlight the System Reserved and drag it to the right to recover the unallocated space giving you a System Reserved Partition approximately 100MB larger than before.

1.4) You may find in this process you have a small remnant unallocated space after C:. In this case Highlight C: and drag its right handle to the right to recover the unallocated space.
Note: When using Partition Wizard the actions are queued until you "Apply" them. I prefer to Apply changes at each stage of the operation than in one hit.

2) Remove system reserved and include its booting functions in the OS partition
Here is a tutorial on how to do this.
System Reserved Partition - Delete
Alternatively:

2.1) Boot the Partition Wizard CD and highlight the System Reserved Partition

2.2) Delete the System Reserved Partition leaving unallocated space.

2.3) Drag the C: partition to the left to take up the unallocated space.

Again I would perform the "Apply operation" at each stage.
Now your Drive will not be bootable because System Reserved contained important booting information. This needs to be transferred to the C: partition. This is done by booting the System Repair CD/DVD and carrying out a System repair operation 3 separate time rebooting between each application. This is described in more detail in this tutorial
Startup Repair - Run 3 Separate Times

3) Use other 3rd party imaging software
Macrium Reflect is highly regarded and comes in both free and paid versions. The link is to the free version. There are altenatives both free and paid.

Note: If you have a System Reserved partition it should really be on the same Disk as your OS.
